What it is
Muscle fibres need certain proteins to stay strong and repair themselves after use. In this inherited disease that upkeep fails, and fibres are lost faster than they are replaced. The muscles shrink and stiffen, and the body has less strength to call on. Because the muscles of the throat and gullet can be affected as well as those of the legs, eating and swallowing may change too.
The disease progresses slowly, and the first signs are easy to put down to age or lack of fitness.
Life with an affected dog is about pacing. Short, regular walks keep it moving without exhausting it, and non-slip floors make getting up easier. If your dog struggles to swallow, let it eat calmly, watch whether food comes back up and give it a rest after meals.
Signs you may notice
- Tires quickly on walks
- Short, stiff steps
- Thinner leg muscles
- Brings food back up
- Struggles to swallow
You may notice a dog that tires sooner, moves with short, stiff steps and whose muscles, especially on the legs, look thinner. Some dogs bring food back up after eating or struggle to swallow.
When to see a vet
Book a visit if your dog tires sooner, walks stiffly or brings food back up after meals. A dog that coughs, breathes fast or seems unwell after bringing food up needs a vet the same day.
