IF you keep using it! It doesn’t work overnight and you may not even see results for a few weeks, but stick to it! That is the key if it is going to work for your dog, not all things help all dogs. I have a four year old dog who gets seasonal allergies starting every spring and lasting until late fall. Her skin gets dark pink, she bites, chews and licks constantly until her fur is a rumpled, crusty mess and we deal with hot spots as well. Until now NOTHING I have tried has had more then a minimal effect and that is a long list of things we’ve tried! Nothing! This year we are doing allergy testing and will try the oral allergy treatments. In the meantime I came across this and decided to give it a try. After all, why not try ONE more thing when you are desperate for something that helps. We are 3/4 of the way through our first bottle and I am amazed! My dogs itching and scratching is not gone but it is reduced by I’d say 90%. She sleeps better now and she doesn’t spend her days scratching and chewing at herself and is just so much happier. I feel like she doesn’t scratch any more then my other non-allergic dogs. I am thrilled to see her feeling better and being more comfortable. Bathing is so important as well, be sure to use a good, soothing shampoo every couple of weeks during allergy season, or whatever your dog needs. We are still going ahead with allergy treatments but will continue to use this to keep her comfortable in the meantime.
