I am going to use this idea. Deja is muzzle trained. I just have to convince the staff that 'gentle and careful' won't work for her in this setting. Thanks a bunch!
We start as low stress as possible at my clinic - there are some dogs that can stand still with the owner petting its head and I can get blood from a rear leg, but if you restrain the dog at all it completely loses it. As long as the dog does not try to sit, this is fine. This is an exception, though. Most dogs (98%) need some form of restraint in order to accomplish anything treatment-wise. 5-10 seconds feels like forever to hold still if a needle is in!
We love owners who are realistic and use a basket muzzle as needed. We don't hold grudges, and always use whatever method is least traumatic to our patient...but no one likes getting bit.
Your dog honestly is one that, if healthy otherwise, we would just sedate. Come in, hang onto your dogs head, we pop an injection in and wait. Once puppy is asleep, we do a full exam, draw blood, x-rays, whatever. Give dog a reversal drug = everyone happy and everything done no hassle.
You could even just pop a pill into a treat before you go to the office. Trazadone is one we rec to owners of dogs who just don't like their procedures. Talk to your vet about just sedating when you go in. Research the drugs - acepromazine is an effective sedative, but there is some evidence that it does not do much for the dog mentally, and can make the aggression worse.
Best of luck!
