Pup is 14 weeks on Monday so still very young but we seem to have regressed a bit in the toilet training the last few days. So she will pee outside no problem but then not pooing, and then pooing inside. This is after waiting for ages outside and then she starts getting wound up and pulling back towards the house. Am I just going to have to stand out there for hours until she does it? Or keep taking her out every 10 minutes? Any tips welcome.
