First things first, I need to know if this is even possible! I am the owner of three miniature doxens females and they are all spaid. I bought my boyfriend a white lab male for valentines day and now were getting married. My dogs are really territorial, and are frankly just mean. The oldest one is 9, then 8, then 7. It seems that the youngest one is the one having the most problems with it. She won't leave him alone and won't quit following him around the house. And when he tries to play she freaks out, backs herself into the corner and snaps at him. Or whenever he's just layinh there she'll sniff him and then slowly bite his ear or neck? But its not like she's snapping then, just biting? And I can't seem to understand if that is playful or not? please, anyone with any sort of help would be greatlly appreciated! This is the most frustrating battle I've ever gone through and I'm in need of a lot of advice!
