Any photos of him standing up?
Sorry to go on about the weight, I just see soooo many overweight dogs everyday at work and it makes me sad that the owners don't realise the health issues and decreased life expectancy associated with extra fat.
Im sure it annoys the rest of the forum
Oh, and they are soooo cute. The one of them sleeping in the first one is gorgeous
