I have a 10 y/o Pom male (neutered) who has always allowed me to brush him after bathing and blowdrying. Now he nips, cries, growls and runs away when he sees the brush. I have tried everything from treats to cuddling first and nothing works. He's shedding his undercoat and the "cotton balls" are out of control. What should I do? This is a new behavior (1 month or less). Thanks
