Dog Muscle Spasms – what are they?
As pet parents, we're always looking out for our furry friends, so when something seems ‘off,’ it’s totally normal to feel a little freaked out. That’s definitely the case when we see our dogs twitching or having muscle spasms out of nowhere.
Sure, it’s not exactly the most comforting sight, but don’t panic just yet – most of the time it’s nothing to worry about.
We’re going to take a look at why dog twitching and spasms happen, dive into some possible medical reasons behind it, and offer you some tips on what you can do to help prevent it happening in the future.
After all, a healthy dog means a happy pet parent!
Symptoms of muscle spasms in dogs
You’ll usually spot muscle spasms as twitching or tremors in one part of your dog’s body. They’re pretty noticeable, and you can often even feel them by gently touching your dog’s skin.
These spasms are usually a reaction to something else going on, like an injury or another condition. Your dog may show other signs depending on what’s causing the issue and how serious it is.
If you start seeing your dog twitching, here are a few other symptoms you should keep an eye out for.
Lameness
This is where your dog can’t properly use one or more of their limbs, due to pain and/or weakness. Common causes of lameness include broken nails, soft tissue injuries, bone fractures, or injuries to joints.Depression
Dogs are very sensitive creatures (which is one of the many reasons we love them!). Like us, they can experience mood swings that you’ll often notice by them showing a lack of energy, sad eyes, whimpering or howling, and being extra clingy around you. Pain
Dog twitching and spasms can often be happening because your pup is in pain. You may notice heavy panting, howling and changing appetites in your pet if they’re in pain.Peace of mind for your pet’s wellbeing doesn’t have to cost the earth. With a Wag!

What causes dog muscle spasms?
So what exactly are dog muscle spasms and why is your pet having them?
Put simply, they’re involuntary muscle movements that appear as shaking, twitching, shivering, or trembling and may result from any of the following:
- Overexertion. This occurs quite commonly in pets for many different reasons, including illness or lifestyle.
- Neurological damage. This is something you’re more likely to see if your dog is old.
- Physical injury.
Although these muscle spasms are mostly not dangerous, they can still be painful, especially if they last for a long time. Dog twitching and spasms may also indicate a more serious condition, including any of the following:
- Pinched nerve
- Slipped disc
- muscle damage
The chances are, you’ll detect them as tremors under the skin, although if you’d like a proper diagnosis of both the spasms and their underlying causes, it may be worth visiting a vet.
A healthy dog is a happy dog, and one of the key ways to help is by making sure they are eating the right things. We’ve compiled a handy How to Choose the Best Food for your Dog Guide, so you can ensure your pup is getting the absolute best for his or her needs.
Medical causes of muscle spasms in dogs
So you’ve seen (and felt) some of the symptoms, but what are the medical causes (if any) behind them?
Like with so many other conditions that affect our pets, the reasons behind muscle spasms can range from something simple like age, excitement, or just being a little chilly, to much more serious medical conditions that might need quick attention from a vet.
It’s always best to keep an eye on the situation and, if in doubt, consult a professional to make sure your pup gets the care they need.
Muscle spasms in dogs can be caused by a range of factors, some of which are pretty common and others that may need more attention. Here's a breakdown of what might be happening:
Exposure to toxins
Toxins like pesticides, insecticides, alcohol, caffeine, and even human ‘treats’ like chocolate and grapes can trigger muscle spasms in your dog. Overdosing on tick and flea preventative medications is another potential culprit.Infectious diseases
Dog muscle spasms caused by infectious diseases can involve twitching in one or more of their body parts. The effects can range from temporary minor discomfort to long lasting illness.Metabolic diseases
Metabolic issues like low blood calcium (hypocalcemia), low blood sugar (hypoglycemia), or dehydration can lead to twitching throughout your dog's body. If your dog’s twitching, especially if they seem unwell, these could be possible causes.Idiopathic head tremors
Sometimes mistaken for focal seizures, these tremors are common in certain breeds, including Boxers, Beagles and Doberman Pinschers.Diagnosing muscle spasms in dogs
If you notice your dog twitching or having localized muscle spasms, the first thing to do is get them some water and encourage them to rest. Sometimes, this is all that's needed to help them recover.
But if the twitching persists, or if you notice signs like lameness or pain, it’s a good idea to call your vet, who will probably want to ask you the following information:
- Your dog’s fitness and activity levels
- Changes in their medication
- Recent sprains or physical injuries they might have had
- How much water they’ve been drinking
Depending on what’s causing the spasms, your vet might want to run more tests.
It’s also super helpful to ask them to show you where the spasms are originating from. This way, they can target the right area to relieve your dog’s discomfort and prevent further issues.
Keep your dog calm, and don’t hesitate to get professional help if you need it.
Treating dog leg spasms
The good news is that dog leg spasms are often a temporary issue, and there are a few things you can do at home to help your pup feel better.
Treat them yourself
Make sure your dog stays hydrated and gets plenty of rest. Sometimes, this alone can help prevent further spasms. If the spasms or cramps persist, you might want to gently massage the affected muscles. It could help ease the tension. Heat or cold therapy can also work wonders for relieving both the spasms and any discomfort your dog might be experiencing.
If you’re unsure, you can ask your vet about muscle relaxants or pain relievers to help your dog relax and ease the spasms.
Supplements
Nutritional supplements, such as vitamins and minerals, herbal muscle relaxers and electrolytes can provide support for your dog’s muscular system while also helping them heal. Consult the vet regarding the best treatment.Additional treatments
If the spasms seem to be related to a bigger issue, your vet might recommend additional treatments. This could include:- Physical therapy
- Massage
- Surgery in more serious cases to address the root cause of the spasms
If you're feeling uncertain about how to handle it, don't hesitate to reach out to your vet. They’ll be able to guide you toward the best course of action for your furry friend.

The road to recovery
As with most things when it comes to our furry friends, the earlier you can figure out what’s causing those muscle spasms, the quicker you can get them back to feeling their best. Prevention is always the ideal route, though!
Simple steps can go a long way, like ensuring your dog stays hydrated and avoiding overexertion, especially on hot days. Giving them breaks during exercise or walks can help prevent strain on their muscles.
Once the spasms have cleared up, you can help support your dog's muscles by providing them with the right nutritional supplements or a diet tailored to strengthen their muscular system.
Your vet will be able to recommend the best options to keep your dog feeling strong and healthy.

Cheagle

My pet has the following symptoms:
Muscle Flutter
When I pet her back (in the middle, and up to the neck) her muscles visibly twitch, similar to a spasm. She doesn’t react like she’s in pain, but I’ve never noticed this before. What could cause this? Also, I’m not entirely sure if she’s a cheagle—this is a guess.

Hello, dogs have a muscle that runs along the back called the cutaneous trunci. When you touch this muscle is will twitch. This is the same muscle that they can use to move their skin. If your dog is otherwise acting normal I would think that you are just touching this muscle.

My pet has the following symptoms:
Muscle Spasm
My dog is 11.5 year old blue heeler/American bulldog mix. He’s always been in pretty good health for his age and size (80lb). He does have a little hip dysplasia, but nothing that has slowed him down much. Yesterday we had a big cold snap and the dog was extra active. Today he just seems to not feel good. I know his legs/hips are sore so I gave him a spring and then his cbd/hip vitamins. He is eating and seems pretty alert still but when went to run on him just now, he crumpled and wined in pain when we hit his side (not even to his hip yet). It feels like he’s having a muscle spasm/shaking.

Hi there, you are through to Dr Linda.
I'm sorry to hear this has happened; poor boy.
There are a few things that could have occurred here including exacerbated arthritic pain, a ruptured ligament in the knee, a dislocated hip, a muscle strain etc
A vet check would be sensible to determine exactly what is going on.
I suspect very much he will benefit from some prescribed pain relief and anti-inflammatories.
Rest him as much as you can and ensure he has a nice padded bed and is kept warm.
Wishing him all the best.
