Hello. I'm a little worried about my puppy. She is nearly 13 weeks old and has had her 2nd injection. I will be able to take her out on walks any day now.! I've tried puppy pads to train her and all she wants to do is grab them and run away with them to play. She does wee on them occasionally and we always reward her. I've been letting her out in the back garden to do her 'business' and she happily goes and does it but finding recently she's squatting a lot and only weeing tiny bits. I've got her an antibiotic from the vet as they said she could have cystitis. How can I train her to go outside when she's ready to wee instead of squatting in the house all the time? Can anyone help?
