Yes, of course. The earlier you notice a behavioral change and you modify it or if you teach puppies good manners when they're little, you'll be more successful. You can, however, train old dogs new tricks too.

It really depends on the size of the dog, believe it or not. Dogs that are giant breeds, like Great Danes in particular, live a shorter lifetime. We hope they make it 10 years, maybe 12, but that would be unusual. Their lifespan is a little shorter. Small dogs like this live the longest. He's a little 17-pound dog, so his life expectancy would probably be more like 15 years or 16 years.

Vaccines are inactivated, killed, or parts of viruses and bacteria that can affect your dog in a negative manner. They stimulate an immune response without actually getting the animal sick so that when the dog is exposed to the naturally occurring virus or bacteria, the immune system is ready for it and can fight it off.

Heartworm is a parasite that affects the heart. It goes into the bloodstream and when you have adults, they actually live in the chambers of the heart and can affect cardiovascular function, respiratory function, and other organ systems.
