Interesting topic indeed, i'd like to read some opinions based on experience. I certainly think style of the dog plays an important role

I have a female who looks like she's around 18 kg's but weights 20,4 on her proper weight. She was raised in the house and walked for like 1,5 hour every single day. I think a dog who's raised like this compared to a dog who's been on a chain for all his life always weights more because of muscle mass. Dont know whether i should see it as a good or a bad thing. At least they're strong on the legs. Would like to see opinions on this too!
