I found this company relatively easy to deal with, I knew my dog really needed some sort of anxiety medication, but just didn't have it in my budget to have an expensive vet visit so I tried this, and found it affordable and easy! I gave a clear description of her problems and they prescribed a regimen.
I will say, they wanted her to go on a few things and I didn't want to get her too dependent on any sort of mood stabilizer, I wasn't convinced it would be helpful, but they assign like a pill "regimen" so they keep sending the ones I don't use too.
