I found a dog she didn't have a home we have had for over a month but her and my other dogs don't like each other... She pees all over the house because my other two are very hyper and they each are 60lbs each the dog I found is 3lbs and 8 yrs old and she is terrified any voice raised (even squeals like a 6yr old daughter being excited scares her) should I find her a quitter home and get my daughter a dog who can handle the noise??? "She is my daughters now because she can be packed around" NEED ADVICE!!! We love this dog please don't judge just want what's best!!
