Big dog is 6, has a phenomenal bladder and has been known to choose not to wee for up to 24 hours before because she doesn't like the rain, can't find a suitable blade of grass etc. Pup is now 15 weeks old and hasn't had an accident in the house for nearly 2 weeks. Big dog, however, has just done a huge wee on the floor, as she also did yesterday twice, just a couple of minutes after being let outside and not bothering to go. This has been an almost daily occurrence for the last 7 weeks since the pup arrived and it's starting to get me down, as it's a huge amount and is a right pain to clean up.
I appreciate she's probably feeling a bit pushed out and is doing it in protest, but she seems to have accepted the pup and happily plays with him, cuddles up with him etc., so I just don't understand what's going on. I mentioned it to the vets a couple of weeks ago, when she was there for something else, and he said there doesn't appear to be anything physically wrong with her,so she's probably just being bloody minded (his words, not mine!).
Any tips on how I can stop this? She gets let out regularly, but never wees as we haven't got grass and she'll only go on grass, and then only if she feels like it! She's always been an awkward bugger
