Chewy used to bit and be horrible but he is 81/2 months and now he does great when being brushed... if I hit a tangle he gets a little upset but he is good for the most part and the brushing takes a few minutes... He is much better with his bath, just stands there and lets me do it...I trim his face and he is good about that... just holds still...
However!!!! Trimmng the nails and brushing his teeth bring out the worst in him! I let the groomer trim the nails... We use a muzzle becasue we have to. And when I brush his teeth I have to hold the side of his wiskers and he tries to bit and hates it. He is not fighting as hard the past week or so and I am thinking he might be getting the hang of it!!!
Hang in there it will get better!
