Category: Muscle
Breeds documented: 1
Published sources: 2

Overview

In this inherited muscle disease, damage to skeletal muscles can cause weakness and reduced stamina. Some Schapendoes develop obvious difficulties, while others have few outward signs. The associated genetic change is linked to poor muscle repair after damage. Signs often begin subtly and progress over time, but their severity and starting age vary considerably between dogs.

Signs to watch for

Becoming tired more quickly during activity
Poor tolerance of heat and excessive panting
Muscle weakness
Muscle trembling
Weight loss

The age when signs begin varies considerably; early changes may be subtle.

When to get help Book a vet visit for muscle weakness, trembling or reduced stamina.

Diagnosis and tests

A DNA test can check for the variant associated with this myopathy. Dogs with two copies have an increased risk of disease, but the severity of signs varies. Blood tests measure creatine kinase, an enzyme that rises when muscle cells are damaged. Vets interpret the genetic result alongside the dog's signs and blood results.
