Should I take my senior dog to the vet if they begin to be less active?

It's something to have checked out, especially if your dog is normally a fairly active being and they just, all of a sudden, start to decline in how active that they are willing to be around the house. It may then be worth checking out. There are certain diseases and certain types of pain that can cause them to slow down.

Yes, definitely. Without a doubt, a dog becoming less active is a critical sign that something's not right. You do need to get them to your veterinarian as soon as possible. The possibilities could be pain, becoming anemic, and heart problems. There are so many possibilities why a dog becomes less active, so bring them in.
