Dear Prudence,
I carry treats on walks because my dog needs them for various training issues (heeling, listening, etc.). We often see other dogs at a nearby park, and become friendly with some. I’m always happy to give the other dogs treats if their owners are OK with it (I usually take extra just in case), but sometimes there are owners who never return the gesture, even though they also have treats. For example, one will let her dogs bother me incessantly for treats, weakly protest, “X, stop begging,” but when she gives her own dog a treat, she does so secretly, crouches down and turns her back, and palms the treat like a card shark as if she doesn’t want me to or my dog to see. She never offers my dog a treat. Is this weird behavior or should I just get over it?
