You can, but it's not really necessary. Fur also helps protect dogs from sunburn, so if you cut it you'll need to be careful about how much time he spends outside.

Yah. I work at a kennel and dogs come in all the time to get there hair cut for summer. I just recently cut my Border Collies hair and now she is so happy. She runs around a lot more too.

i dont think you should because lab retrievers have very sensitive skin and it could get sunburn very easily

I have 2 chocolate labs and they shed like crazy. If you're worried about dog hair get the grooming tool called the Furminator. It seriously works like the pictures where you see the dog sitting on the floor and their hair is all around it. Just take them outside and it works like a charm!

No. Fur insulates them from the heat as well as the cold and he's only 7 months old and doesnt even have his full adult coat yet. It could take a very long time for his coat to grow in normally at this age if you have him cut.. Labs are supposed to have short sleek hair on their ears and more on their body. It has to do with bouyancy in the water. They are after all a sporting breed.
