If your dog stops eating or is only picking at their food, this might be part of the reason your dog is losing weight, especially if your dog has been eating a declining amount of food over a few weeks.
Getting an otherwise healthy senior dog that is refusing food takes some experimentation.
If your dog is normally a kibble eater and has started turning its nose up at its bowl, it’s possible he or she is having jaw or tooth pain. Many senior dogs have dental disease or teeth removed, and this can make it challenging for them to eat crunchy, hard foods.
Try softening the kibble with water or a salt-free bone broth. Otherwise, you may need to try a semi-moist or canned food. Home cooking sometimes goes over well with dogs that are otherwise being fussy eaters. You can try mixing cooked pork or chicken with rice and sweet potato or pumpkin. Maybe your dog needs a meal change and something new will be enough to spark an appetite. Gently heating up your dog’s food might be enough to convince your pet the food will be tasty.
Changes in routine or environment may put your senior dog off its food for a couple of days, but if there are no underlying problems, their appetite should bounce back.
If your senior dog refuses to eat for 24 hours, contact your vet. If your dog’s appetite was normal and changed abruptly, he or she might not be feeling well.
