My female chihuahua is 3 1/2 years old. She has allergies since 6 months. About 1 1/2 week ago, she was given silica 30c by Dr. Jeff. It has been 8 days - she seems a bit better (mood and energy) first couple of days, then she had a tea tree oil shower, and maybe that antidoted her remedy. Since then she is back to her old self. It's been almost 6 weeks since her cytopoint injection. Normally this is the time for her to get another shot. She has been scratching her neck so much, it is looking very bad - I am afraid she may have an infection there. I do not have an appointment with dr. jeff until this Friday. What should I do -- I am thinking I have to take her to a local vet.
