My 8 month old chihuahua Zoey, will soil her crate. I have had her one month, her crate is very small so I don't think it is that. She has been to the vet and got a clean bill of health. She doesn't do it all the time, sometimes she will go all night. I don't feed her after 4:30 p.m. and she doesn't get water after 7pm. Any ideas!!
First, you will need to clean out her crate completely with an enzymic cleaner such as Nature's Miracle (or the like) - then you will need to remember that she will only be able to "hold it" for her age in months plus one (for example if she is 8 weeks - she should be able to hold it for 3 hours). This may mean you have to get up in the middle of the night for a potty break.
