I have just rescued a 8 week old female Staffordshire terrier/Lab. My girlfriend has a 3 year old, 10 lb male Bichon Frise, which seems to be the dominate one right now. The staffordshire terrier was living with a 7 year old pit mix and a 10 month old pit mix and just followed them around. My girlfriend and I do not currently live together but plan on it in the near future. Could people give me some advice to make this work. Thank you for any help that you could be.
