Oh i know how you feel. its hard to believe that our very sweet looking dogs have hidden horns that erupt when ever they want. and normally when they are not feeling good.

i went through something simular with Kirby when he got really sick. he would be still,, but he kept trying to bite the vet every chance he got. and he managed to do it once but luckily Kirby was so weak at the time it didnt even break the skin. while his tail was wagging through the whole process.

apparently its a nevous reaction or maybe just nurves alone. cant always go by tail wiggles when our little ones are sick. just ask our vet....LOL
