Completely useless
I bought these for my small Jack Russell,(After reading the reviews and measuring him very carefully as advised) I ordered the small size. The nappies arrived and I was quite excited as I was hoping we had found the solution to our problem. I put the nappy on him and unfortunately,although it did fit him round his waist it is not deep enough to cover the offending article. I endeavoured to persevere and tucked his winkie in the nappy only for the nappy to slip off as soon as he started walking.
