Need immediate help with our JRT
We have a beautiful 4 year old JRT, she was a make a wish gift for our son. The whole family loves her to pieces and she has brought much joy to us. Recently she has started fighting with our 9 yr old cock-a-poo and has injured her. All over territory of a bed or couch. Last week she got into a fight with her and bit my husband while he was breaking it up, badly enough he got 6 stitches on his forearm. My dog training friend, whom is a godsend is suggesting we adopt her out due to the fact we have teeanage children and a very active home. I am sickened over this. I am looking for other options as far as retraining. Any ideas?
PS... neither dog is allowed on any furniture anymore and I am reiterating the alpha role specifically to the JRT. The cock-a-poo was already extremely submissive before the JRT ever became part of the family.
