Puppy just not getting toilet training

[alleg]

18 week old Cavapoo.

I take her out every 15-30 mins, say the command word whilst she's doing her business and the reward with a high value treat.

I'm not sure whether to keep on with the command word as when I say it she will stop mid wee/poo, so ends up doing loads of tiny wees.

If the back door is open when I'm in the kitchen, she will take her would out every time without fail to toilet, so she knows to go outside?

However, she still wees and poos in the house a lot.

I'm not sure what to do? I've been toilet training her for ten weeks now.

To be fair all the advice on this thread will just be advice read online, even if it’s been written by a person with 50 years experience with animals.

Keep going OP, I’m sure it’ll all click into place soon. I do think rewarding as soon as she’s finished might be better than halfway through.

Dogs have no idea that the treat is for the LOCATION. They think the treat is for the action. If you treat for “going” in the right place they just think you like them weeing and can start to bop down in front of you in the house hoping for their wee treat.

Same principle as punishing them for weeing In the house - they assume weeing is dangerous and start going off and hiding to do it. No understanding that you’re punishing the location.

Just be more vigilant, keep quiet when pup is weeing so you don’t interrupt, and they get there in the end.

I wouldn’t use treats. That can encourage them to do tiny wees to get more treats. Just praise.
The more often you get a pup outside when they need to go the fewer accidents and quicker they get it. So after drinking and eating and playing and sleeping and at very regular intervals too. If they don’t go then back out v v soon. And watch them like a hawk inside too.
Don’t know what was up with PP. Maybe they needed a wee?

Some dogs get it quickly and some don't, like kids 😂 I had a spaniel that took 6 months and a Labrador that took 2 weeks. Keep going OP and ignore the unpleasant individual who resorted to throwing insults.

This is the key piece of info (IME).

It tells me she has already started to form the habit of toiletting outside and may be trying to indicate she needs a wee and you are missing it. Very easily done because...

a) whatever she is using to try to tell you is often at the mercy of whatever she thinks it is that works. It could be anything, even something as daft as her looking towards the left (based on a true story).

b) often at this age their tells are small, somewhat varied and not always reliable. For example, my own dog would sit down. That was it. Just sitting down (anywhere) was how he started to ask to be let out. Over time we have tweaked it to him sitting, facing me and staring at me. Good enough.

I would focus new efforts here. Lots of people get on well with a toilet bell the dog rings to be let out but whatever you want her to do, ask her to do it immediately before going into the garden. Do that often enough and she should link the two and start to use it herself.

On the (somewhat bad tempered) debate about cues and rewards:

Cues are useful but not mandatory. There is many an occasion I want the dog to wee now because I know he won't get a chance for a while. It's useful to have something to tell him to do so.

Rewards I am ambivalent about tbh. For the most part, needing a wee is uncomfortable and the relief of weeing is a good feeling and so often reinforcing in itself. Praise is probably harmless and may even help sometimes. Food or toys can more often be distractions that cause more complexity than they solve.
