What is muscle atrophy in dogs? It sounds alarming, but what does it look like and how can you help your four-legged friend? Here’s a quick overview.

What is muscle atrophy?

Muscle atrophy means when the muscles of your dog’s body weaken or waste away. It usually affects a dog’s back legs, but it can also occur in the head or the belly.

Signs to look out for

If your dog is experiencing muscle atrophy, the first thing you’re likely to spot is that they’re not enjoying their walks in the usual way. It could be harder for them to walk normally, their legs might look stiff, and they may seem less comfortable moving around.

You might also notice that:

  • Your dog’s hind legs seem thinner and they’re using their front legs more to compensate.
  • Your dog has lost weight and it’s easier to pick them up.
  • When you stroke your dog, the muscles feel flabby under their coat.
  • Your dog might drag their paws.
  • They might cross their legs as they stand or walk.

Breeds susceptible to muscle atrophy

German Shepherd

Certain breeds are more likely to suffer from types of ‘myopathy’, which are diseases that cause damage to muscles and can lead to muscle atrophy. There are two main categories of breed: large dogs such as German Shepherds and sighthounds such as Greyhounds.  

In the first category, German Shepherds are prone to Fibrotic Myopathy which causes weakness in their thigh muscles, Labrador Retrievers can be affected by Centronuclear Myopathy leading to muscle loss in their first year, and Great Danes can inherit a disorder that causes muscle wasting.

Some sighthounds are also affected by muscle loss, but for completely different reasons. When a breed such as a Greyhound experiences Exertional Myopathy, it’s usually because they have over-worked their muscles through intense activity.

The double whammy effect

If your dog suddenly loses a significant amount of muscle, we’d always recommend talking to your vet to find out if it’s a sign of a more serious underlying condition.

However, very often muscle atrophy is caused by the ageing process or a lack of activity. Put the two together – an older dog who’s not getting much exercise – and you have a double whammy that could bring on the condition.

The causes of muscle atrophy

Let’s have a closer look at these two causes.

  1. Getting older.  A certain amount of muscle atrophy is normal as your dog gets older. Like humans, older dogs produce less growth hormone as they age and are less able to break down and synthesise protein to help build their muscle mass.
  2. Lack of exercise.  This is a case of ‘use it or lose it’. Your dog needs enough exercise to keep their joints, ligaments and muscles strong. Without the right amount of exercise, they risk losing muscle mass.

How to support your dog

Once you’ve ruled out any serious underlying cause for your pet’s muscle loss, here are a couple of practical steps you can take to support your dog.

  • Enjoy a stroll together. Exercise will help build your dog’s muscle tone and mass, so get that tail wagging again by taking your dog out for a gentle stroll. If your dog has been finding it difficult to walk far, take it easy to start with and ask your vet for advice on the right amount of exercise for your pooch.
  • Give your dog a great diet. Additional weight will add more strain to your dog’s muscles and make it harder for them to walk. So make sure you feed them a wholesome, nutritious diet that will help them stay in condition. Look out for foods that are high in protein and fat, and avoid those that are higher in carbohydrates and fillers.
