[Frenchy]

I have a new foster,he's 18 months old,a real sweetheart,loves my other 3 dogs.Only one problem,he has a very sad past,being left by his owner on a farm,nobody took care of him,got hit by a car,then again was left uncouncious for 4 days without anyone helping him!He broke a tooth in the process so takes more time for him to eat.Since the others finishes before him and gets close to him and watch him finish his food,he shows them teeth and growls a bit,not a lot.I really wish for him a new family with a dog to play with/keep him company.Is there anything I can do to help him get over this food issue?I do keep my dogs out of his way when he eats but wish I could do more.please help.
