tvet.com We all know how important regular checkups are for us as we age, well, this is no different for our dogs. As a matter of fact, when you consider how much faster our dogs age, these checkups are even more critical and should be even more frequent. A pet's body goes through many changes as he or she ages, and many of their systems can begin to breakdown as well. We can be much more effective in helping them deal with these changes if we catch them early on. It's often much easier to prevent the big problems than it is to treat them.
