Tonight when my little Livvy came to the door after being out for an hour or two...I looked and couldn't believe what I saw...her nose was about 2 x's as big as usual...and of coarse she didn't want to come in so I had to bribe her...got the benadryl out and gave her her size dose...It still is somewhat swollen and I called the vet but it is sure nice to have this on hand for emergancies and it saved me an after hour visit to the vet...I believe she either bit a bee or wasp...I'll probably never know and I'm still watching her closely! It's just one of those "must have" thing corgi owners should have for allergic reaction!
