Dog with recurrent hives
My dog (11yo female neutered Labrador) has been on prednisone(2.5-5mg)day for 8 yrs.for allergies(itch).9 days ago developed bad hives on face and body after routine vaccines(aug.9) and extremem itch- 1st time ever).I assumed it was a reaction to shots and treated with benadryl(with a vet's advice). 5 days later happened again though,(aug 15) and has lasted for four days but I had changed her brand of food that day(Aug 15)(still lamb and rice formula though). My gut says it's the food but is is just a coincidence that it happend also before the food change due to vaccines? I'm so confused - benadryl helps but head keeps getting hives - body too. My vet says usually vaccine reaction would have under 1 hour after and she was 3 hrs so unlikely from the vaccines. She is so swollen until I medicate her - then hives subside till next day. Nothing else new in her life.Should I go back to previous food? This happend one other time two years ago - we guessed then it was our lawn sprayed for weeds or an insect bite but that time it cleared up after two days. Now has been 4 days. Please help! |

Dog digging carpet
My dog (5yo female neutered Blue Heeler mix) is outside during the day and inside at night. I've only had her for 6 months- I got her from a friend. During the past month, she started scratching at our carpets ruining them. She only scratches them around the walls never in middle of the floor. Why is she doing this and what can I do to get her to stop?
