I have 2 puppies, Benson, a 21 week old Maltese x Shih Tzu and a 19 week old Bichon Frise x Maltese, Molly.
Molly was going along nicely with her toilet training but all of a sudden she is refusing to do a wee on the grass when I take her out and instead, will come back inside and do it in the house. She sometimes also wee's when you go to pick her up, like this morning. They both sleep in a wooden playpen beside my bed and I went to get them out this morning but before I could reach Molly, she went and weed all over her bedding.
I'm wondering whether there is a medical reason for this, such as a urinary tract infection or whether it's just behaviourial issue.
Any advise would be appreciated.
