Hi I am new to the dog forum and looking for some help and advice. We have a 6 month Jack Chi puppy and a 4 year of the same breed. The puppies toileting is causing us problems as she is unpredictable. She can go through the night with no problems and 3 - 4 hours during the morning and evening before we take her out to do a wee. The problem is that a couple of other times during the day she will pester to go out 3 times in an hour doing a wee each time. We thought it might be a behaviour issue but if we ignore her after her first visit then 10 minutes later she will wee in the house. She has seen the vet and a UTI was negative, we have tried putting her in a crate but she gets distressed. During the day the two dogs do play fight and chase each other so we thought this may be causing the problem as she may drink more after playing. But we think that at 6 months she should be able to hold her wee longer than 3 times in an hour. She is a tiny puppy more chihuahua than Jack Russell as she only weighs 2.5kg. We would appreciate any help or advice for us to understand why she wants to wee 3 times in an hour when we know other times she can hold it in.
