Maintaining your pet's house is crucial to ensuring longevity and supplying your dog with a clean, homely environment. Depending on the type of pet house, you should clean it regularly. If it's an outdoor doghouse, you may need to clean it weekly or bi-weekly, while an indoor cat house may only require cleaning once a month. Use a pet-safe cleaning solution and a scrub brush or hose to remove debris or dirt. Pests like fleas and ticks can infest pet houses, so check regularly for signs of infestation. If you notice these, treat the pet house and your pet promptly.
