My little puppy seems upset with me lately, and I'm worried that it's because I haven't been able to spend as much time with her the past few days. When I'm not home, I have to leave her in her crate (nothing unusual), and I have a dog walker take her out for a lunch time potty break. Usually, when I got home and took her out, she'd jump all over me, wagging her tail - but not now. The other day, I went to pet her and she grunted and scowled at me, then walked off to play with my brother who was visiting. Then, that night, she refused to sit with me on the couch like she usually does. Then, just earlier, she gave me a dirty look, and when I tried to pet her anyway, she growled at me - like MEAN growling, not playful puppy growling. The look in her eye was pure evil. It scared me to the point that I went in my room and locked the door. I want the puppy back that I used to know and love. Who is this awful little creature who has taken her place? All of this leaves me to wonder if my dog hates me? Thoughts?
