The dog is a Yorky poo, very easy to groom, but nervous about his feet. The cat on the other hand is part Main coonand tabby. She weighs about 24 pounds. SHe has long-haired, several very thick matted hairs. She will not let me groom her. I have sedated her in the past to be able to groom her, but shes gotten smart to that and wont let me sedate her anymore. both pets are 9 1/2 years old. Please help me.
