[Mee-sha]

Its been a while since i've been on here.sorry if this is long.Meeshas been recently diagnosed with collapsed trachea.it began to appear this summer. I'm now having issues with trimming her nails, she gets so stressed and anxious she gets to a point she can barley breathe, it scares me so i end up being unable to do them, i've been massaging her feet as a baby , give rewards etc..shes fine with me touching her feet, fine when i trim the fur on her feet with sissors, but when it comes to nail trimming, she screams(yes not cry , she wails as if shes being murdered) , shes always been like this but i got through it. Now i can't get through it because he breathing gets so bad shes going to pass out. the only one who can do it is a vet tech. my other dog milo who dosent have collapsed trachea is the same way but i end up having to stop because he not only gets anxious(unlike meesha hes fine because he can still breathe) he hits me in the head with his head, bites the nail clippers and scratches me... so both dogs i can massage thier feet trim thier feet, but go pshyco when i try to trim thier nails, i've tryed rewards, putting a blanket over thier eyes, had other people help, but cant hold them still enough, to get the nail trimmed...what can i do , its 18$ each plus tax for nail trims, it just cost me with tax 42$ today. with all of meeshas vet bills for her ct, i was wondering if anyone had any other suggestions for how i can trim them myself...meesha is 3 and milo is 1 years old.
sorry that was so long, i just thought id give it one last shot and see if anyone else had a yorkies like this, and were able to overcome it and how?
