Loss of appetite in Labradors
Loss of appetite (medical name: anorexia or hyporexia) means your pet is eating significantly less than usual — or not at all. A single skipped meal is usually nothing; multiple skipped meals signal something needs attention, especially in cats where prolonged anorexia can cause hepatic lipidosis.
About Labradors
Outgoing, energetic, food-driven, and America's most popular dog for decades. Large, athletic, prone to weight gain.
Health predispositions in Labradors
- Hip and elbow dysplasia
- Environmental and food allergies
- Ear infections (especially after swimming)
- Obesity-related conditions
- Bloat (gastric dilatation-volvulus)
- Progressive retinal atrophy
Predispositions don't mean your individual Labrador Retriever will develop any of these conditions. They just mean these are seen more often in the breed than in the general dog population.
