I need some help with Boston he dont like my little male maltese/pom however he does like my male Bichon. Is it maybe b/c Bear is smaller or maybe b/c I have a female in heat. I really need to get him straightened out or my husband says he'll have to go Bear was here first. They are all fine in the house but the second that front door closes look out Bear he traps him and just barks non stop then he goes for his tail an draggs him around kind of funny but Bear Hates it. Please Help I love him so much and hate to see him go. Any Suggestions are much needed.
