I thought my pigger had mites by the way she was acting: biting herself, itching herself a lot, not enjoying lap time...etc. So I figured I would give her a couple rounds of ivermectin to see if the symptoms would go away. I've given her 2 treatments and so far I haven't noticed any changes. She still eats just fine, runs her piggy laps, popcorns. But she still squirms a lot when we pet her/hold her and bites our fingers and constantly bites our shirts if we're holding her. She still has been itching and biting herself a lot but no hair has fallen on excessively besides some light and normal shedding. I came to my own conclusion that she either doesn't have mites, or she's not responding to the oral treatment that I've been giving her. Should I try doing the topical treatment instead? I know she should probably go to the vet but I want opinions before I spend more money than I need to. Thanks!
