Nice story about your dog. That's really cool that you were able to help it and get it back feeling normal again. It's tough for a dog that wants to run around.
Everybody wants to cut but nobody wants to diet. If you're not dieting you're not gonna do much on a cut like this. I would definitely make sure that you really tighten up your diet strongly.
In terms of dosing I think you'll do fine with 2-3mgs a week. That's going to be an optimal amount to run. Some people will go to 4 or 5 mg but I don't think it's necessary.
It's interesting how cannabis can affect things. I've read so much over the years, especially the way it messes with estrogen, so that's an interesting one.
