We have a 10-month-old bullmastiff puppy, female, spayed. She's staying with our rescue mix, who she has been raised with, while our two-year-old boxer is going to another home (earlier thread, fights in the house, thanks everyone for thoughtful responses). To give us a little time to place the boxer, we've farmed out the bullmastiff to a two-week board-and-train.
When she comes back, there are a couple of things I want to look at. One is pacing. She paces morning and night, when she's excited, when she's hungry, when anyone else is up and moving around. She'll have her head and neck straight out, not stiff or up or down, just forward, and she likes to carry something in her mouth when she does that. Tail as well, not up or down or wagging much, just level and swaying back and forth just a little. Her steps are sort of long and very deliberate. When she greets, she'll do that in a circle around you and snort a lot. There aren't any signs of aggression to it, but it gets annoying and it seems to stress other dogs.
Any ideas what that's about?
Other thing is leaning. She leans on you like a bag of lead. Everyone loves it, really, because she's doing it for affection -- lean into you, put the whole weight of her head on you, do the puppy eyes thing. Everyone melts. Petting and baby talk ensues, never fails. That's exactly how we brought the boxer up spoiled rotten and contributed to his possessiveness. The last thing I want is to repeat that mistake with a 120-lb guard dog with a head the size of a watermelon. I want to discourage dominant leaning, because she's already figured out how to use her weight to push other dogs out of the way -- what's to stop her from trying it on us? At the same time, I don't want to discourage affection. That's what's so lovable about this dog, the way she's just loves on people.
Thoughts?
