| Some dogs are just small, just like some people are just small. As long as he's healthy, I wouldn't worry about it. Also, please remember that weight in and of itself isn't very important, it's his overall appearance that matters (weight + height + build, etc. In other words: does he look healthy). However, if he's *skinny* and won't gain weight even if you increase his feedings, you may want a second opinion from another vet: there are many different diseases and parasites which can cause a dog to lose or not gain weight. |
