Why is my older dog so lethargic and always sleeping? Is it normal?

Updated On September 23rd, 2025

Pet's info: Dog | Yorkshire Terrier | Male | unneutered | 5 years and 11 months old | 7 lbs

This might sound silly but, I was reading an article I received in my email from this app, about signs with your dog having cancer. Well, I'm a bit worried about Prince.. all he does is sleep. Unless we are going on a walk, I know he's older and maybe that's a reason why. But he doesn't play, he's not friendly to other dogs, every chance he gets he goes lie down and gets his rest. Should I be concerned or is this normal for dogs or dogs his age?

At 3years of age he would generally expected to be more active but every dogs character is different and some are very placid. If his behavior has changed over the last 3 months I strongly recommend a full health check by your vet to rule out medical or painful conditions which may be reducing his mobility
