I have a 7-month old shih-tzu/ poodle cross (mostly shih-tzu). Housebreaking has been an ongoing battle ever since she came home. She is slowly getting better at it, but still wees and poos in the house even though she is taken out regularly (hourly) when not asleep. I know that she can hold her bladder for 5 hours, as she does that when crated- she isn't usually in there for more than 4 hours at a time, but there have been a couple of times when I was late getting home due to an accident on the roads and there being no buses and on every occasion she was fine, it has even taken a 30-min walk to then produce a result.
This is our current set-up-
7.30am up and out for a wee and a poo
8.30 food then straight into her crate whilst I take my daughter to school
9am get back from school take the dog for a 45min walk at the park, whilst there she poos and wees at least twice. rewarded with chicken and me stroking/ praising her (not sure how much of my praise works as she's deaf, but I am banking on my body language here mostly)
9.45-ish back home. She will then do a wee on the floor within 10 minutes of getting in, even though she always does one just before we get into the house
10am-ish crate till 2pm, she sleeps the whole time
2pm another 15min walk, usually a wee or two, then home and play with me/ 15min training session
3pm crate for 30min whilst I get my daughter from school
3.30pm another quick toileting walk, then playing some more. An indoor wee is guaranteed to happen within 15-20 min of being back home
4.30pm toileting walk, sometimes she does a wee, sometimes she doesn't
5.30pm food, then remains crated for an hour whilst I cook our dinner/ we eat. This also more or less guarantees that she actually goes once taken out at 6.30pm. A wee shortly after we come back in
7.30 she goes back in her crate as it's my daughter's bedtime and she is not allowed upstairs as she is guaranteed to wee/ poo up there. She also can't be left downstairs alone for the same reason, even when taken out for a wee and doing one just before going upstairs
8/8.30pm, another quick toileting run and after that we play for a bit and she just goes to sleep under my chair whilst I work. Usually she sleeps for about 3 hours, or until woken to be taken out again before being crated for the night, midnight usually.
Chicken as a reward for a successful wee/ poo is given every time she does it outside, so is praise!
So, as you can see currently she spends quite a bit of time in her crate because she can not be trusted to be out of it. We have tried extending her crate area/ allowing her to be in one room only so that it's more manageable for her but it makes no difference- she just pees there and then anyway, even if it's on her crate's doorstep, so to speak. Also, she has no signal for when she is about to go- there is no circling, sniffing, looking at the lead/ door/ Jesus- nada. She will just walk, walk, walk and then drop her ass, wee, and carry on walking as if nothing happened. Same with running. She has even managed to do a wee whilst walking up the steps to get into the house!
Also, the thing about house wees is that they are tiny amounts, more like marking her domain I would say- no idea if bitches do that though.
So yes, any advice you experienced people could give me, would be greatly appreciated.
