Shetland Sheepdog Health Problems: Symptoms and When to Worry
The most common Shetland Sheepdog health problems are collie eye anomaly, MDR1 drug sensitivity, and hip dysplasia. Shetland Sheepdogs typically live 12–14 years. This page is organized by symptom, so you can jump straight to eye, joint, hormonal, and immune problems, see what each one looks like in a Shetland Sheepdog, and know whether it is a vet visit this week, a vet visit today, or an emergency right now.
Quick answer: when to worry about your Shetland Sheepdog
Go to an emergency vet now if you see any of these:
- Eye: Sudden blindness, a bulging or very painful eye, or an eye injury is an emergency. Glaucoma, a scratched cornea, or a prolapsed eye can cost the eye within hours.
- Joint, back, and mobility: Sudden inability to use the back legs, dragging the hindquarters, or crying out when touched along the spine is an emergency. A ruptured disc has a window of hours for the best outcome.
- Hormonal and metabolic: Collapse, severe weakness, or vomiting with lethargy in a pet with a known hormonal condition (Addison's, diabetes, insulinoma) is an emergency.
- Blood and immune: Pale or white gums with weakness, bleeding that will not stop, or a fluffed-up bird or small pet sitting on the floor of its cage is an emergency.
- Any pet: collapse, seizures lasting more than five minutes, uncontrolled bleeding, or an inability to stand.
Book a vet visit this week if you see any of these:
- Eye: Book a vet visit for any cloudiness, redness, squinting, discharge, or a change in how they navigate a room, especially at dusk.
- Joint, back, and mobility: Limping for more than a day or two, stiffness after rest, reluctance to jump or climb stairs, or a change in gait.
- Hormonal and metabolic: Weight gain or loss without a diet change, increased thirst, hair loss on the body, a pot-bellied look, or lethargy.
- Blood and immune: Pale gums, unexplained bruising, nosebleeds, fever, or a pet that is off color for more than a day.
Keep watching if: the change is mild, your Shetland Sheepdog is still eating, drinking, and moving normally, and it resolves within a day or two. Write down what you saw and when; a dated list is the most useful thing you can bring to a vet.
