Hey Isabel, I'm so sorry your SWD is suffering from this shot (guessing it was more than just Lyme, however, but maybe not).
The fix is explained in my free Apoquel Alternatives Report, which you can download when you join our Vital Animal Pack (also free). You'll see several ideas there, but the one with the greatest return is the first: hiring a professional, trained homeopathic vet. Don't be shy to do this, as the quicker you get this "nipped in the bud," the better the results will be. The converse is also true: lots of trying other things that "sort of help" and coming to the professional after months usually means the path to curing this is much longer.
All the best to you both.
