I'm right there with ya, girl. Potty training's a drag...
Saydee's 17 weeks and I still let her out about every 20-25 minutes, all day long, just to be on the safe side (unless she's napping). If you set a timer for every 20 minutes and just take her out, it may help you to avoid alot of the accidents altogether. Doggies Lucy's age can pretty much go on demand after about 25 minutes and it helps if she knows there's no playing, or going back inside, until she gets the job done. I know it's alot of work, but every accident you avoid gets you that much closer to the goal.
I don't use pee pads because I prefer Saydee think it's never acceptable to go potty inside, period. You might consider this approach simply because your breeder encouraging potty on blankets is gonna make it tough! How is Lucy supposed to know that peeing on clothing, blankets, towels, even rugs, is unacceptable? That seems like it might take alot of patience on your part to break that habit
All the more reason to not even let her get to the point where she feels the need. I know it's very time consuming, and trust me I get so frustrated I want to cry when Saydee pees on my bed after all the effort I put toward training. But I have to remember how young she is, and that every time I catch her in the act, and redirect her outside, it's a good thing. I never let her out of my sight and I'm always on high alert. I don't yet trust her to make the right decision just because she did the time before, so I still put her in her crate any time I can't give her that supervision.
Every single week gets better, and I'd have to say that Saydee's about 98% there. It's just that last 2% I've gotta shake!
I hope this helps. From one puppy mommy to another, I'm pulling for ya!
