My name is Charlie!

We got charlie from Facebook about 4 years ago. He's been so good to us and in return we have given him a nice life as well. About 2 years ago we brought in a new dog that is a little big bigger than him. Both are poodle mixes. They've been really good buddies over the last 2 years but I'm not sure if charlie has any issues ( mentally ) but the last 4 days he's been really aggressive towards the new dog. He is only aggressive with the dog. With humans he is so good but he just gets scared to open up anymore when the other dog is around. Charlie I believe would make a great companion for an older couple or even a nice young couple. We would love to keep both dogs but even then I fell on hard times with hours cut and back taxes that drained my account. Eventually we may have to get rid of our 2nd dog as well but we shall see. Again charlie is good with me and my wife but he's been super aggressive with the other puppy as of late. We would be sad to see him go but to the right situation
