okay Eris is only 4 weeks old. Someone is getting rid of their female jack russel who just weaned a litter of pups she is good with other dogs and puppies. I was thinking about taking her into my home. I think eris will benefit from her,she will get the lessons her own momma would of given her and be around another dog? The Jack russel is 5 years old and they are giving her away for free. What do you guys think? They are going to bring her over to meet Eris and hopefully she likes eris. I want eris to have the oppurtunity to be around another dog.
