Hi, well as for me there are not so many options, if you want a universal solution that will not hit your wallet and bring pleasure to your doggy, then I can advise from myself special pads for urine for small breeds of dogs, they are quite a lot of varieties, but personally I chose for myself small dog potty pads from "PottyBuddy"
https://pottybuddy.co/products/small-dog-potty-pads . The pee pads from PottyBuddy are perfect for small breeds of dogs, as they provide reliable protection against leaks and odors thanks to their high quality absorbent materials. Their compact size and ease of use make them ideal for small pets and their owners, ensuring a fresh and clean home at all times. They are also reusable and easy to clean. I hope I have been helpful with my advice. Good luck!
