2 crazy weeks. But, I doubt we'll keep it on her that long. She couldn't potty last night because it was on. She couldn't get her head down to sniff and ended up falling over. This morning I took it off so she could eat and drink. She was more then excited to be able to eat. She refused the wet food with medicine on it and gagged at first. So, we had to force it down straight. Then, she wouldn't eat her own food, so I let her eat Pono's. I let her wash her face and sides before putting the cone back on.
