Sam, i do know Beau had gotten to where he was hardly humping at all here. I'd say UH UH BEAU and give him a real stern look , then he'd run over and sit by me
NOW perhaps since he's adjusting to being with your , your family and cacao this might be partly normal as to establishing order so to speak.
also Peanut would put Beau in his place if he tried too much.
So now Beau is with you for 2 weeks and a 3rd doodle is introduced
so now the real fun begins and so does humping
since it's for the weekend i wouldn't worry much as it's not like having 3 dogs permanently.
Fixing Beau will help ........but even fixed dogs can do this
It's a bit of work but keep saying NO or UH UH ...whatever they respond too.
I found that Beau when told UH UH and then he came and got petted his humping really decreased. it was like getting a treat for NOT humping :wink:
