So I have been faithfully brushing Gucci's teeth since he was a baby ... I got him when he was just 9 weeks, he is now 9 months... and he is NOT having it. He was OKAY with it up until around 2 months ago when he got Kennel Cough. I let him have his way and didn't mess with him too much during the 2 weeks he was really sick because I felt so bad for him and didn't want him to go through more than he had to

(my mistake!).
Anyhow, he started to get really ansy after he got better and EXPECTED me to let him have his way ... Yorkies are obviously very smart like this and catch on quite quickly

. After a couple of weeks he started to get in the hang again but then he got really sick again (vet thinks poisening of some sort but we cannot be sure) and I AGAIN let him have his way. EVER SINCE THEN HE'S BEEN JUST TERRIBLE!! the hair we can get through, even though he's a total brat about it. The teeth however, he just goes ballistic and I don't know what to do. Every night it's a fight and he's panting like there's no tomorrow from both anxiety and the battle and he is just completely worked up and nippy even

. He does get corrected and has NEVER EVER Bitten me but he's jumpy, whips his head around, and kind of nips but not at me.. at the toothbrush... Like GO AWAY!
Now really it is such an episode that I can't help but laugh at him towards the end. I just don't know what to do, how do I get this back to normal?
Any Suggestions?
