Big, big problem!! My gsd is extremely attached to me. My wife is 85% bed bound. The dog comes to my wife’s bedside, gets treats and petted. Never been a problem. Now, for some reason, when she walks by him, heading to the restroom, he growls. Once he gave her a small nip, once he snapped and growled. I’m at a loss. My wife’s a dog lover and has always been nice to Max. I DO NOT want to give him up, but don’t know what to do.
