Benefits of Neem for Dogs. Neem leaves and neem oil benefit dogs in numerous ways. The leaves can be used to boost the immune system of dogs in general, and to repel intestinal parasites. Neem oil can also be used to treat skin problems, repel fleas, mosquitoes, and ticks. Read this page to see how neem can benefit the health and wellbeing of dogs.

The biggest problem with neem pet products is that many commercial neem pet shampoos or neem sprays also contain other essential oils, in particular tea tree oil.
