My Pochi will be 2 yrs old tomorrow. YAY!! and is puppy pad trained BUT he has a thing for plastic bags(like from the grocery store or any type trash bags) he will see it and if left to roam alone there is no doubt he will mark on it! I don't know why he chooses to do that on them! It's quite frusterating! Everyonce in awhile he will sneak in a piddle on the bathroom shower mat (especially after I wash it!
How convenient huh?) hehe
I know he knows it's wrong because whenever he goes and "marks" on something he makes a mad dash to our bedroom and sits on his bed and shakes with his head lowered down.
Now Choppi (we got him when he was 4 mo old and now he's 10 mo old), he does great one day no messes everything on the pad and the next day he acts like he doesn't know what a pad is and does his 'business' everywhere BUT the pad.
Daisy is great!!! From day 1 never had a problem with her. She gets it right on the pad. Except on a couple of times when she's smelled a spot where the other 2 have pee'd on in the past...so I can't really blame her.
Meeju is our mini schnauzer and we actually have her trained to go potty outside and usually never have a problem with her.
Maybe it's just co-wink-i-dink (coincidence) that the boys have a harder time with the potty thing than the girls. hmmmmm
Funny thing now that I think about it, the boys in my family (human, funny that I have to clarify yorkie or human) had a tougher time potty training as kids than the girls.
