Hi everyone, I'm new to this forum. Looking for some help for my pup, Pocket. She's a 1 year old great dane x greyhound (I think she has a bit of am staff in there too), and we've had her since 4 months as a rescue. I've had my 11 year old lab Josie for her whole life. Since we got Pocket, she's been very attached to my husband, and prefers him over me. In the beginning, she would bit a bit snappy towards me, and snarl or bite if I disciplined her, or either of us were giving attention to Josie. We've managed to successfully train that out, and she hasn't snarled or snapped at me in over 6 months. However, she still does this to Josie. It's particularly around food or attention, and I'm not sure if it's resource guarding or just the pecking order, and I don't know if it's harmful or normal. The most common scenario is food, we are now able to feed them side by side if we are watching, but if we walk away before Josie has finished, Pocket will jump over and snarl at her to steal her food. My old dog is a giant sweetie, so she just lets Pocket have whatever she wants. If they're playing, Josie is still top dog and can wrestle her down, but as soon as it's serious Pocket is the boss. Secondly, the one that worries me more, is usually when I come home after work and cuddle them both, half way through Pocket will just turn on Josie and snap and snarl at her. I don't think she's ever hurt her or drawn blood, but it sounds awful. She very rarely does this in front of my husband, but if she does it's because he's paying attention to both dogs, not just her. I'm worried this behaviour will escalate, and she'll hurt Josie one day, or worse, a child. We don't have any kids yet but hoping to soon, and I don't know how to fix this behaviour. Any help welcomed!
