Do not feed your pet the following: chocolate, garlic, onions, nuts, avocado, artificial sweeteners. (I dont get the nut stuff ... because in one of the challenges a groomer got to use peanuts for their dog treat ....?).
Sequins and rhinestones from doggy costumes can be choking hazards.
Never cut a cat whiskers. The whiskers are a cat's sense of touch and balance and assist cats in walking through narrow spaces. (I cut Betsy's whiskers once. Probably why she never jumped on tables or countertops).
