I asked before about getting another chihuahua. I have another question about it. I have a 10 month male chihuahua. Over the weekend I took in my friends 5 month old beagle. It was an emergency situation. My puppy barked and growled for awhile, but then left her alone. The next day when he saw she was still here, he started shaking and would not leave me. He would run from her, if she came by him at all. I had another friend then take the beagle. Now I am concerned about getting another puppy. Do you think Poppy had a hard time because she was bigger then him, or because it was a different breed of dog? I have heard chihuahuas only like their kind. Or do you think Poppy would not do well with another puppy. Thanks for any advice you can give.
