Hi,
Cattro also had bruised ears for weeks and weeks after me poking her ears. She was very good and I was very careful, having been shown in the vet's office and also looking at utube and reading up on it. When I mentioned this to my (then new) vet, he told me that it's possible to test on the pads of the feet. (he did have a DVD somewhere but couldn't find it at the time. ) This has proven to be a godsend for me and Cattro. Some people wash and dry the area first, but I just wipe and poke. I also use a very small torch to light up the area while doing this - Cattro lies still so I just rest the torch nearby - and I also use the see-through cap of the lancet which, when pressed back onto the beginnings of a drop of blood, draws the blood up and creates a larger drop that is more easily tested, sort of a vacuum effect. I also used to warm her feet up beforehand if possible: fleecy blankets, hot water bottles [yes, with all the safety precautions that go with these] worked well for us. At first she wouldn't let me test her front feet but after 14 months she is fine with all her feet, but hind feet easier. (not sure how much feeling she has in them, she is 21 years old! )
Good luck,
Kay
