NO WAY! I think it would be really obvious if my greyhound was even a tiny bit overweight. She has always been a skinny girl. Lucky.

A funny story:

I was at a dog park once and Jenny was playing with some other dogs when a boy {6 or 7 years old I'd say} came in with his mother and lab. I was sitting on the bench and didn't mind when he started chasing Jenny with his lab. After all, I thought, they'll never catch her. They ran past me and I realised he was chasing her trying to pet her calling "Skinny Dog, Skinny Dog" I called Jenny back and let the boy pet her...I guess, now that I think of it, she really is a skinny dog.
