Chloe, remember, there is a difference when a vet is talking about a dog being healthy and a dog being overweight

When they say healthy they mean good clean teeth, no diseases or parasites, good coat, bright eyes, etc. At least with my vet and others I have consulted that is the way they are. I think they do this because sooooooo many North American pet dogs are obese they want to let the owner know their dog is for the most part healthy and compliment them on that, and then tackle the weight issue seperately. I dont agree with this personally as being overweight can lead to health problems.
I love it when I hear people say ""He''s not fat he''s just very furry"" LOL I have a furry dog and I deal with dogs with even more fur than both mind put together LOL Fat does not just magically disappear because ones dog has a a lot of fur....ah well Personally I''d rather see a dog a lil on the skinnier side than fat, especially in larger breeds. Its amazing how many peopple see a well-conditioned dog and claim that he''s emaciated!
