The medication I bought from Pet360, if not fake, may as well have been.
Within a few weeks of changing my dog's medication, from what I had been getting from the vet to the medication I bought from Pet360, my dog declined from walking (with some instability) and being able to get up the deck steps, to no longer being able to stand.
On the chance that it was due to the medication I bought online instead of a rapid progression of the disease, I stopped giving him the Pet360 medication and bought more medication from the vet. Within about 2 weeks, he is almost back to baseline.
