Elka's weight, to date, has not been a problem for us to maintain, and well. The fact that she's oversized (i.e., taller than she should be) is added incentive, as I don't want undue stress on her joints. Those need to last her a good long while, you know!
Pet obesity can be a problem, though, especially because dogs and cats are ultimately at our mercy for food. We can feed them adequately, or too much, or not enough. Adequate is the goal, obviously. A dog (or cat) in a home setting isn't necessarily hardwired to stop eating when "full". What does "full" mean to a dog, anyway?
So:
Name: Elka
Sex: Female
Breed: Doberman
Age: 3
