To preserve your toys for longer, it’s important to carefully check them after use to ensure they haven't started to wear down or break. You should also clean your dog's squeaky toy before putting it away. While you can't put these toys in the washing machine, you can gently hand-wash them using warm water and soap. If you need to get rid of a lot of mud and grime, you can use a sponge to carefully scrub away extra dirt. After that, use a towel to pat them down or air-dry.
