I adopted a dog from the humane society a few months ago. She has shown some aggression towards my small dog that I have had for 4 years. My dog will walk past her and she'll jump up and start barking and growling. I told myself I would work with her, etc.
I am dogsitting my parents dog (golden retriever) and she (shelter dog) went after him this morning for no reason and just now did it again but this time she bit my parents dog. Not hard but she definitely put her teeth on her.
I am really upset. I am seriously thinking of returning her even though the thought breaks my heart:(
