You don’t have to wash your dog tent after each use, unless it smells heavily of wet dog or there are major stains. Use simple house materials like water and lemon to wash your tent. Make sure the dog tent is always dry and that your dog is as dry and clean as it can be before it goes into the dog tent. You can go a while without having to wash the tent, unless it starts to smell like wet dog over time. In that case, scrub the tent with gentle materials and let it air dry. That way, you’ll take care of the materials it’s made of and also get rid of the wet dog smell.
