Please use crates!! The crate on the left above is allowed by airlines, the one on the right is not (both are medium size crates). We prefer the one on the right, your puppy can feel closer to you.
Crate train your dog!! You are not punishing him/her and they will see their crate as a safe haven.
When traveling, it will be safer for your dog in case of an accident.
If you decide to feed your dog a RAW diet, you don't want raw meat around your house.
