OH Girl I FEEL YOUR PAIN!!!! RIley is six months old, and he hasnt got it quite down pat yet, we have the pee pads down and if he has to go He will go on them, but when I take the dogs out I say "Come on guys lets go pee" and when I see them go I praise them, ( my neighbors think im mental Im sure) because im out there acting like a nut out there clapping and carrying on..lol But I sounds to me like you are most likely doing what you can, and the problem is your husband!.
.....I go through this with my hubby as well..I just tell him to quit complaining since he is not the one that has to clean anything up!...I also tell him to get over it, the pup is not going to get house broken any faster just to please him, and his complaining is just a waste of time, and if it bothers him that bad when the dog has an accident then he can get off his but onced in awhile and take him out....
....Oh they get on my nerves...But hang in there your doing your best no matter what hubby says.
