I have 2 dogs, a male & female both around 2 years old. They are both generally well-behaved, and respond to our commands. They get along well - sleep together, play chasey, share dinner. However, when we get home after being away for more than about an hour, our male dog goes a bit crazy and tries to play-fight with our female.
He doesn't bite her or show aggression, he just jumps around her like he's trying to get her attention, makes a weird growling/bark noise (doesn't sound aggressive) and mouths her (she ends up with gross slobber all over her fur). She doesn't really respond to him, just kind of looks annoyed.. she kind of cowers a little to just avoid him, because she's trying to get to us for a 'hello' cuddle.
We're able to get him to stop at the time (sometimes by pointing and looking 'disapproving' at him, or distracting him for a cuddle) but he just does it again the next time?!
We're not worried as it's not aggressive and just playful, but I just don't understand the behaviour? Plus it really annoys our female and takes all the fun out of our 'hello' cuddles
Also, he doesn't do this if he's just been sleeping when we get home (he still gets up and gets excited, you can just tell he's been sleeping from his slower, happy whole-body-wag)
Also also, he does this behaviour even before we've entered the house.. they see us at the fence and that's when he'll start.
Any advice is appreciated!
