We have a 16 week old German Shepherd who we’ve had since 8 weeks. Around 9 weeks of age he was diagnosed with parvovirus and survived. Since March 17th he had been eating a bland diet, on antibiotics, and no other treats of any kind (to stick with the bland diet). We recently put him back on a special dry kibble to help him gain weight. Our trainer had us practice putting our hands in his food and petting him while eating. Sometimes, he’ll growl when we do this, sometimes not. I’ve read up on Adrienne’s approach of giving him a high value reward while walking by or standing by his dog dish. Sometimes, he’ll growl with us just standing there and sometimes not. If he growls, do we still give him a reward? I understand the concept of making them excited to have you walk by, but it also feels like we are rewarding negative behavior. I’d love to hear input on this please. I should add, he is other wise mostly cooperative, we can take toys from him without any issue. He is fine around other dogs and no other aggressive behaviors seen.
