What is Urinating Foam?

It can be a little concerning if you notice your dog is urinating foam. You need to watch closely when your dog urinates to try and determine if the foamy appearance is coming from your dog’s body or if it is bubbly and foaming when the urine comes into contact with the ground. If the urine looks foamy when it comes into contact with the ground, this may not be a cause for concern, especially if the weather conditions are very cold or very hot. 

Foamy urine may be a sign of excessive protein in the urine and could be a symptom of kidney failure. This is called proteinuria. Many times this is characterized by changes in urinary habits, appearance, and smell of the urine. If you suspect your dog has excess protein in their urine, you need to make an appointment with your veterinarian quickly. 

Some dogs that urinate foam may also have an infection in the kidneys or in the bladder. You may notice that your dog is straining to urinate or they seem to feel pain when they urinate. This is a condition that needs to be quickly diagnosed by your veterinarian. 

Medications can cause your dog to urinate foam. Prednisone and other steroidal medications can cause your dog’s urine to appear bubbly or foamy. Antibiotic such as Temaril or Clavamox can also cause foamy urine. Possible causes of why your dog is urinating foam include:

  • Proteinuria
  • Infection
  • Medication

Why Urinating Foam Occurs in Dogs

Proteinuria

Proteinuria is when there is an excessive amount of protein in the urine. This will cause your dog to urinate foam and is a main symptom of kidney failure. Your dog will need to be seen by your veterinarian so diagnostic tests can be performed to determine whether or not your dog is going into kidney failure. Once your veterinarian has determined proteinuria as a cause of your dog urinating foam, they can then discuss treatment options with you. 

Infection

Urinary tract infections or kidney infections can cause your dog’s urine to appear foamy. When your dog urinates, you will see foam or bubbly urine. You may notice a change in the color or smell of your dog’s urine. They may be straining to urinate or seem to be in pain when they urinate. All of these are symptoms of an infection. You will need to make an appointment with your veterinarian immediately for diagnosis and treatment.

Medication

Certain medications can cause your dog’s thirst to increase and they will consume for water. When they drink more, they will have to urinate more and their urine can appear to be foamy or bubbly. Steroids such as prednisone and antibiotics such as Temaril or Clavamox have been known to cause dogs to urinate foam. If you notice foamy urine, speak with your veterinarian about possible side effects of any medications that your dog is currently taking.

What to do if your Dog is Urinating Foam

Anytime you notice something that is off with your dog, you should take time and fully assess your dog’s health. Monitor their water consumption, how often and how much they urinate. Also note how much foam or bubbles are produced when urinating. When you go in for your veterinary appointment, this information will help your veterinarian know where to begin their search for the correct diagnosis. 

A urinalysis will help determine if your dog is suffering from an infection or if there is excess protein in the urine. Once the diagnosis has been made, your veterinarian will discuss treatment options with you and prognosis. After a treatment plan has been decided, be sure to follow instructions carefully and ask any questions about side effects and timeline for recovery.

When your dog is on medications, be sure to ask questions about side effects. If the medication that your dog is currently taking may cause your dog to urinate foam, then you need to let your veterinarian know that your dog is experiencing this side effect. Changes in medication may be necessary if the foamy urine is excessive. Your veterinarian may need to re-examine your dog before concluding that the medication is causing the problem.

Prevention of Urinating Foam

Proper diet and plenty of clean water will help your dog to not develop an infection. A clean environment, including clean bedding, will also help prevent bacteria or dirt from getting into your dog’s urethra and causing an infection. 

General check ups will also prevent your dog from becoming extremely ill from excess protein or an infection. Your veterinarian will be able to hopefully catch any changes within the urine and treat any problems that occur.

Hello I'm sorry to see that your pet is not feeling well. If he is vomiting, then you should take him to a veterinarian right away. They can give him medication to stop the vomiting or do some diagnostics testing to figure out what is going on. The doctor might want to check his urine for a urinary tract infection. Good luck.

If you think that there is an abnormality with Coco's urine, it would be best to have her seen by a veterinarian, as they can examine her, look at a urine sample, and see if she is having a problem. They would be able to recommend any needed treatment once they know what might be going on with her.

Gets Tired And Will Sleep If Someon

Hi, First of all thank you so much for your service. God Bless You for the love and donation of your time. My dog is 2 yrs old. He is house dog. We put him on leash to pottie or we take him for a walk so we have not noticed foam in his urine until today he potties in the house and it was a good bit which was a big pile of foam. I don't think he drinks enough water. He doesn't drink until he is real thirsty or comes back for. His walk. He is part poodle and jack russel and looks like a snouser with a beard. You can te he doesnt like the way his face gets wet when he drinks. I dry it sometimes. Yes he is spoiled. Lol However He has been panting for a while when he does any kind of physical activity. He hasnt been panting as much lately. I can tell he does feel good sometimes. I read foam could mean too much protein or infection. He also has anal problems which we just had vet express them. He was swollen real bad and hurt on his back near his rear so I thought this had something to do with him not feeling good. Although he never turns down a walk or play time. He does not want to eat dog food very much. His daddy buys him a new bag to try almost every week to no avail. His treats are duck jerky or chicken jerky, sweet potatoe duck sticks, sweet potatoe wrapped in chicken jerky or peanut butter biscuits. As I said spoiled. He gets several treats a day. Starting when he wakes up. Now dad ( He's friend) lol is cutting a duck jerky strip in his food. He will eventually eat it. When he won't eat and we have meat he will eat that. Sometimes he sneaks and eats the cats food. That was all he wanted to eat for a while. I read that wasn't good so I put her very little at a time now so he does eat some it is very very little. Explained his ratting habits and life style to see if we have contributing factors to this problem. Off course I spoiled him although he has his daddy wrapped. Don't mess with his boy. Lol. And he does throw up every now and then. Usually yellow color with foam. Not often. Anything you can tell me to help this matter would be greatly appreciated. I am not working right now and dont have money for vet. God Bless You!!!!! That k you so much.

Foam is not a usual finding in urine but a few bubbles are; make sure that you witnessed the urination as foamy liquid vomit can look like urine. Infections, protein in the urine and kidney disease (leading to protein in the urine) are the usual culprits of foam urine; I understand your financial position but a simple urinalysis test (simple dipstick test) would be valuable in assessing protein/bacteria/blood/glucose etc..., request a sterile sample pot from your Veterinarian’s Clinic. The urinalysis will give a strong indication of a possible underlying cause and your Veterinarian may be able to direct treatment inexpensively from there. Whilst urinalysis is inexpensive, your Veterinarian may recommend ultrasound and blood tests as well; there are many charity clinics which may be able to help you as well as national organisations (see link below). If protein or kidney disease is the cause, a low protein diet would be best and the cutting out of treats too; a special wet food diet slightly warmed up may be appetising to BamBam, also offering smaller portions more often may help with the vomiting.

Not Pooping As Much
Foam In Urine

We rescued Buster 3 1/2 years ago, he has been great so far. He was starting to go blind when we got him, but that hasn't stopped him. Earlier this evening he had some white foam in his urine. He rarely poops when I take him out in the morning, usually doesn't do that until 1 in the after noon and it's not as much as it used to be.
