We have a king charles cav puppy 15wks old who is fab in every way, toilet training was a breeze' until last week, she has suddenly started wetting on the sofa, floor, anywhere! but only if my husband is on his own with her, I have no problems. I work during the day and my husband has changed his shift to evenings so she is not left on her own. She is very excited to see him when he returns at night, and sometimes wets a little on his shoes which we put down to excitement. But now she has started doing it if he leaves the room. She is also displaying quite submissive behaviour towards him, tail under legs etc which is upsetting him enormously. Has anybody got any advice, as he feels as if she is frightened of him and would like to know the best way to change how she reacts to him. Thanks.

He hasn't accidentally startled her has he? Or has she been accidentally scared by some strange man in the park perhaps coming to pet her but (to her) looming over her in a scary way? Make sure you don't get cross when she does the submissive weeing as this will make her do it more to try and appease him. Does she like playing with toys? He could perhaps sit on the floor with a toy and gently encourage her to interact with him (not calling and insisting she comes to play, or playing too boisterously). Experts please! :-)

I agree that he shouldn't loom over her, but sitting on the floor with a toy or treat is a good idea, however i think it would be even better if he didn't interact with her at all just sat there taking no notice of her and let her find her own way over to him, let her sniff and get used to him again, then play gently or give the treat when she is calm (not tail between legs).

Dogs are creatures of habit, and it could simply be she isn't used to him being around in the day and finds it unsettling, and reacts submissively as she is that way inclined anyway.

Thank you all for your replies, its really helpful because we have been doing the opposite, we have been encouraging her to play boisterously with him, chasing and barking and generally rough games, thinking that would give her the confidence to be the dominant one! We dont shout or fuss when she wee's, and she will interact with him, in fact she sits on him and sleeps during the day. I encouraged him to give her treats from her tub when she goes out to wee, but in the last 2 days when he gets the treat tub out she runs into her crate and wont take it from him!? There are 3 things we think may have caused the reaction, on one of her first walks a man fussed her but unfortunately then stepped on her! My daughter had a real tantrum a couple of weeks ago and my husband shouted at her, maybe the dog thought it was aimed at her? also he has been the one who for the past 4 weeks has had to leave her on her own to go to work, she definitely knows his routine and her behaviour becomes strange when he is getting ready to go, maybe she thinks this is punishment.
We will try the gentle play approach, any more ideas gratefully received, as hubby was desperate for a dog and is very sad he cant interact normally with her. She is still very young and hopefully will grow out of it and be the soulmate he wants!!
