He could have more coat than your Lucy, and since summer is hear it is very natural for them to shed. Especially if he, himself, is still in the process of making a big adjustment to a new home. If he has been rescued, he has likely changed hands a few times and been through a LOT. It can take a long time for them to realize they are in their furever home, and any amount of stress (even if it is not noticeable) can cause hair loss.
Have you ever taken your dog to the vet, or even in the car, and all of the sudden it seems like the hair is just falling out non-stop? Whenever my girls go to the vet they shed profusely!!!
I know of two things that CAN help with shedding: Good Quality dog food (we love Avoderm) & Wild Alaskan Salmon Oil.
I would not worry about it too much. Just try to do what you can for him, but those are the only two things I know of that can help ease the shedding.![]()
