My husband and I just adopted a 3 month old Cane Corso a few days ago. He’s very sweet, but learning he is definitely stubborn. From the very first time I fed him, I have been hand feeding. However, last night when I was feeding him his dinner, and stroking him and saying his name gently like I’ve read you're supposed to do, I noticed him tensing up. I picked up some stray pieces of food that had fallen on the ground with my other hand and place them in my feeding hand and he growled and bit me lightly. Not too hard, but enough to break the skin. I know he is just a puppy, and he is in a new environment, but I am concerned about this behavior because I have had many dogs in the past and never had this problem. I am just looking for some reassurance and tips that if I continue to hand feeding that his resource guarding won’t continue?
