My Husky is in no way an aggressive dog. She’s never showed this behavior in her life. However, I’m watching a 1 year old lab for a week who isn’t fixed and he’s a male dog and she’s a female. Which probably has something to do with it. He’s crate trained which is good. She’s not though. Whenever I let him out of the crate he doesn’t leave her alone. He’s obsessed with her. He makes a mess of the house chasing her around. He even knocked over the TV. The only time I can let him out is when they’re outside together. I spend about 6 hours outside with them because I don’t want to leave him in a crate all day. He just will not leave her alone and she gets so annoyed she attack’s him. She try’s to growl and snarl for the first 15-20 minutes and walk away but he follows her and continues to push her to the point where she attack’s. I’ve had to take days off work this week to spend as much time as possible outside with this dog. I’ve taken him on hour runs, played fetch, let him roam the yard for hours and I’m just exhausted. I just don’t know what else to do with him. When I try to lock her in a room he just goes to that door and barks. When he’s in his crate he’s pretty calm. But I have to put a blanket over it most of the time because when he sees her he goes nuts. She’s 7, so she’s old and wants nothing to do with the poor guy. Any suggestions? I’m losing my mind here and want this puppy to have an enjoyable stay but it’s not gonna be enjoyable if he has to be kept locked up most of the time. During the night I kept him in the room with me instead of the crate and shut the door and left her out but he cried all night.
