Safety is also a consideration. In September 2018 the US Food and Drug Administration (FDA) released a statement warning about the risk of tremors and seizures in animals treated with products containing drugs in the isoxazoline class, which are used to combat fleas and ticks. However, the FDA said it still considers the products "safe and effective".
Combing and brushing dogs regularly is essential, particularly for longhaired breeds. It is best to establish this habit early in a dog’s life so that grooming becomes part of the routine. Grooming removes dust, dead skin, loose hairs, grass seeds, and tangles. It also assists to shorten the coat moult, which occurs every autumn and spring. Brushing helps keep your dog cool in summer months and reduces the amount of hair your dog sheds. Dogs with short coats also require some brushing.
