What is Bacterial Infection (Streptococcus)?

There are good and bad bacteria in all of us, including our dogs. Once in awhile, a bacterium causes an infection and makes your dog ill. This usually happens because your dog’s immune system is low for some reason, such as a recent illness or with very young or old dogs. The Streptococcus canis bacteria is one that can cause an infection and illness in your dog. Since it is already present in your dog’s body, it does not take much for the bacteria to cause an infection if your dog has recently been sick. This is also common in puppies that are not immune yet and older dogs whose immune system is weak. When a dog’s immune system is weakened for any reason, it is easy for the Streptococcus canis bacteria to invade areas where they do not belong and cause a bacterial infection.

Bacterial infections (Streptococcus) is a common infection caused by a naturally forming and necessary bacterium. This bacterium are usually found in the dog’s respiratory system, intestines, urinary, and genital tract, but sometimes cause isolated infections in a dog anywhere in their body.

Diagnosis of Bacterial Infection (Streptococcus) in Dogs

Diagnosing a bacterial infection from Streptococcus canis in your dog depends on the symptoms and what your veterinarian finds with a physical examination. The vet will need to know about your dog’s medical history and whether there have been any illnesses or accidents recently.

 After a physical examination, the veterinarian will need to do several lab tests:

  • Complete blood count (CBC)
  • Blood gas and chemical panel
  • Urinalysis
  • Bacterial culture
  • Fungal culture
  • Throat and nasal swab
  • Skin scrapings and biopsy
  • Allergy testing

 If the veterinarian suspects the infection has spread throughout your dog’s body, they will take some digital radiographs (x-rays) of the chest and abdomen area. Your veterinarian may need to do an ultrasound, MRI, and CT scan as well.

To rule out any other disorders, the veterinarian may also do an endoscopy and laryngoscopy. An EKG or ECG may also help the veterinarian rule out heart problems.

Treatment of Bacterial Infection (Streptococcus) in Dogs

Treating the bacterial infection from streptococcus canis depends on where the infection has infiltrated. The veterinarian may want to hospitalize your dog while giving him IV fluids and antibiotics if the infection is severe or causing life threatening symptoms. If the infection happens to be in your dog’s skin, your veterinarian will apply topical antibiotics and ointment and send you home with the medicine and antibiotics. Be sure to follow the veterinarian’s directions carefully to get rid of the infection. It is essential you do not stop giving your dog the medicine when he is feeling better. Give your dog all of the medication as directed until it is gone or the infection will come back and be even worse.

Recovery of Bacterial Infection (Streptococcus) in Dogs

If your veterinarian schedules a follow-up appointment, it is important that you show up. The veterinarian will give your dog a complete physical examination to make sure the infection is completely gone.

Be sure to feed your dog high quality food and fresh water, use stainless steel food bowls, and call your veterinarian if your dog gets worse or if the symptoms go away and then comes back. Give your dog plenty of exercise, including walking every day and maybe the dog park on the weekends.

As long as there are no complications, your dog should be completely recovered and ready to get back to his normal activities within a week.

My 1 year 5 month old Pomeranian has been lethargic for over a week, she started limping on her front right leg 4 days ago, then limping on her hind left leg 2 days ago. She barely eats, but when she does eat she’s very picky (wet food only). She has several abscesses all over (4 on her back, 2 around her mouth) - 2 just “popped” last night (they were bleeding). The vet did a chem panel all normal (CBC showed elevated white cells & liver alp a little high). X-ray was fine (no pyometra found). Waiting on cultures - which takes a week. She’s been on antibiotics 4 days and no signs of improvement. She pees when I carry her outside and her poop is still solid...she’s never vomited.

It sounds like Breezie has a severe infection, four days is still early in treatment in cases this severe and may take much longer; it is useful that a sample has been sent for culture and sensitivity so that the most suitable antibiotic may be determined and used for treatment. Apart from continuing treatment as prescribed, I cannot recommend anything different at this time. Regards Dr Callum Turner DVM

I’m curious as to how the dog has turned out. I experienced something similar and vets have no idea what it was. I think it started with my dog being depressed a month prior. She also lost a little weight. But her being a husky we figured since we just brushed about a thousand pounds of hair off her that maybe that’s why she looked more skinny. She had her annual appointment on may 5th and seemed fine. She was good a week later. After that (about may 18th/19th) she started limping on her front left paw. And we saw a “scab” on her back left hock and her head. We figured she hurt herself going under our bed. She was limping about a week. The last few days she just stayed under the bed and wouldn’t come out. I had to hand her food and water. On may 26th we noticed she would shake when she laid down and just looked so miserable. On the 27th, she stayed in her cage all day and i noticed her pupils dilated, her blue eyes were yellow, and she was warm. I also noticed sores on her paws/between toes on the back legs and that one scab on her hock wasn’t a pea size anymore it was on her whole ankle bone. She would “clean” it. I made an appt to vet on Tuesday since it was memorial weekend (not open Monday). At her appointment (may 29th) her vet said her temp was 105.3 degrees, blind and dehydrated. I took her to the hospital that day. They did CBC which they told me had signs of inflammation, gave her iv fluids for half hour, and told me she had more sores than i saw. They were on her tongue, mouth, and more on her toes. They gave me an antibiotic, gabapentin, and eye drops. Did a valley fever test but didn’t come in until that Thursday (may 31). The next day i thought she was a bit better because she drank a lot more. Thursday the same. Valley fever was negative. And they gave another antibiotic, prednisone and antifungal. Couldn’t get antifungal til Saturday. Friday however, i noticed her breathing wasn’t the same, and heard fluid in her lungs. She had a red tinge color of drainage on her nostrils as well as her right nostril swollen closed. More sores popped up and got worse. Her tongue had red dots all over it and the sores were bleeding more. Her nails and gums were turning bluish purple/grey. And she was weaker and weaker. Saturday (June 2) it was so bad. She couldn’t stand to go to the bathroom, her sores were worse. There was one i noticed that Wednesday that was red and by Saturday it was purple/black. We made the hard decision to put her to sleep because we saw the decline was so quick and she was just so miserable. She was just 1 year and 5 months. She was lethargic, had pain and swelling in her limbs, the wounds kept “popping up”, fever was gone after the hospital visit, it affected all of her systems, nervous system (sudden blindness), heart, lungs, skin, she didnt even respond to her name on the last day. Multiple sores on her tongue as well as ulcers on her gums and mouth, no response to meds either. I got a copy of her records from hospital and the blood panel (to me) revealed she was also in liver failure. She had a lot of normal low/high levels that were borderline. Anyway, i know that’s long but i’m Just curious as to how Breezie ended up. This is the closest i could find to what happened with my husky.

The signs that you are describing aren't likely caused by the Bravecto, but might be a bacterial, fungal or parasitic infection that needs to be treated. Since I can't examine Hunter, I can't diagnose what might be going on, and he should see your veterinarian. Hopefully it is a simple problem with a simple solution!

Anemia
Fever
Lethargy
Frequent Urination

Our 9 month old wire haired pointing griffons (littermates) have gotten sick a few times since we got them in August. Mostly together (a day or so a part), but sometimes only the little boy. Our vet has has no luck in diagnosing them, but says it's probably a bacterial infection. They keep testing them for various diseases coming up with no positive results other that he is anemic and has had a few UTI's. She now wants to test him for "rabbit fever" and limes disease. Something is either causing him to get sick (we live on a cattle ranch with cows, chickens, barn cats, elk, deer, etc so they're exposed to poop, mud, etc). We are looking to get a second opinion, but are drained financially and emotionally as it's hard to watch him in pain. When he's at his worst, he will get high fevers up to 105, super lethargic - won't get up off bed or couch, even peed in his dog bed the other night and just laid in it all night, won't drink or eat, is clammy/sweaty with his fevers with shivering (just like a human, didn't realize dogs would have those same symptoms with a fever) so needless to say, it's hard to see him in pain like that. He even moans and groans when he's at his worse as if he's having body pains or aches. It's awful. Any input would be super helpful? Anyone seen these symptoms before? No vomitting and some runny stool, not always full on diareha, but definitely soft usually. He pees alot, not frequently, but for 3-4 times longer than his sister. He has always had more runny stool, we've changed his food twice as our vet said he has a sensitive GI system and always poops/squats 3-4 times rather than just getting it done in one squat like his sister. He used to also have a problem holding his urine - he'd tinkled all around the house even if he was potty trained and would go by the door. It would just all the sudden hit him or he wouldn't have control it seemed like.

Some dogs get sick more than others and on a cattle ranch there is a never ending supply of material which may cause a dog to be sick, especially if they are immunosuppressed. Infections, parasites, toxins, foreign objects among other causes can lead to similar symptoms; a test of the faeces to look for particular pathogen would be useful along with sensitivity testing. I cannot point out a particular cause due to the vague nature of the symptoms and their correlation to infections. Regards Dr Callum Turner DVM

Constant Need Of Peeing. Dhiarhea

So our Stradforshire terrier who has IBD Had a Cyst that was removed. He was placed on antibiotics while his sticthes which were located very close to his butt healed. After about a week and a half of healing we noticed the stitch area was red and swollen. We then took him in to get the stitches removed and placed him on the recommended antibiotics which were from a pouch and cant remember the name. So now he is having problems peeing none if any comes out, and his poo is soupy with dhiarrhea. he does not appear to be in any pain and plays, but the vet said the test shows he has urine in his blood, and she felt en enlarged enflamed prostate....Could it be some sort of infection from the antibiotics,,,He was fine and doing great as always before the surgery and Antibiotics. Any suggestion might help. I hear streptocaucus infections can cause this...She is administering antibiotics for the inflamed prostate.

If Spencer is not neutered, prostate disease can be an underlying problem. Antibiotics would not cause an infection, but there may be complications related to the location of the surgery. WIthout knowing more details about his situation, it is hard for me to comment, but if he isn't improving, it would be best to follow up with his veterinarian, as they can see him and know more about his specific situation.

My 8 yr old Maltipoo has an itchy skin bacterial infection on different areas of her body. She had her annual vaccinations yesterday and I was given Rilexine antibiotics to be given 2x per day. THE Vet called this morning with her blood test results and left a message that she wanted to talk to me about the blood test, but she had to leave a message. I'm still waiting for her to call me back. I gave Annie her first dose last night. She refused to eat anything today and appears very restless, laying down but fidgety as though she can't get comfortable. I haven't given her anymore pills as I'm concerned she's having an allergic reaction to the meds. I'm really worried about my little girl.

Without knowing more about why your Veterinarian wanted to speak with you about the blood results, I cannot really comment; Rilexine (cephalexin) may cause a stomach upset which may lead to a loss of appetite, vomiting, diarrhoea and other side effects of administration. Wait to speak with your Veterinarian before doing anything else. Regards Dr Callum Turner DVM https://us.virbac.com/files/live/sites/usa-public/files/pdf/PI/Rilexine%20PI.pdf

Not Eating

Freckles is a Beagle mixed with something else. He was 13 years old. He's been pretty healthy except for a lump of fatty material that his vet said it was common in older dogs. It didn't seem to hurt him or bother him in any way. Three weeks ago we traveled out of town. Made a stop at a dog park mid point of the trip. The first full day of being out of town, I got back from work and noticed him limping. He'd hurt himself before jumping from the couch to the floor. Where we were staying had stairs, so I thought he had tumbled down the stairs. His leg wasn't broken though. Then he stopped eating and started becoming lethargic. The vet treated him for bacterial infection. I'm curious to find out what would cause a bacterial infection in him?

First of all, thank you very much for having such a great program. Our dog is a three and half year, black lab, 82 lbs active(runs loose twice a day in the woods and on the golf course in the late evening when golfers are finishing up. She and her older Pit/lab 7 1/2 yr old do this activity together. The pit/lab never gets sick and the both share the same swampy/clean streams of water holes. The lab keeps getting sores, scabs and smelly discharge half way down her frontal neck. Sometimes it goes away and then it returns. I try to use the collar as little as possible. What can I put on her sore to clear up the infection, what are the possible diagnosis from the vet?. Any information would be greatly appreciated in preparation for the trip to the Vets office, thanks again

Wound Infection, Delayed Healing.

German shepherd pup, 7 months old, had torn scrotum from dog park dog fight. Vet stitched him up same afternoon with dissolvable stitches and put him on Enrofloxacin 68mg BID. Head cone applied, but pup was able to get it off. Licked wound, no chewing/ripping. Little swelling. Secured cone with shoelaces and has been secure since. Wound partially opened with some purulent drainage about 3-5 days post op. Continued with med, but was not healing. Returned to Vet and med switched to Ciprofloxacin 500mg. BID 8 days after surgery as well as sent out a culture/sensitivity. During this time, I read that these meds should not be used on puppies under 1 year and can cause joint damage. Med given for 5 days until CS results returned. CS returned with alpha hemolytic strep and leclercia adecarboxylata 13 days post op. Vet switched to Amoxcillin trihydrate and clavulanate potassium 500mg per 12 hours starting today. Wound appears clean and trying to heal these last few days, altho a surface scab comes off repeatedly and wound reopens. About 1/2" long x 3/8" wide now. Was double the size. Dog remains inside and activity severely limited until wound heals completely. Appetite good, excreting good, behavior good. Most concerned about possible joint damage or tendon rupture. What's your take?
