Sorry for the long response I don’t believe the medicine ever helped him, I was giving him this for 2 weeks and although he doesn’t gape too often after drinking I saw him gape like 2 days after the 2 weeks was over. When I first got him a year ago I never saw him drink but when I sprayed he would run up and stick his tongue out at the sprayer so I gave him water like that every time he would come up for like a month and I saw him gape 2 separate times back to back so I looked it up and realized that’s very bad. So 6 months later (which is a couple months ago) I see him tilting his head back pretty much every time after he drinks and sometimes does small gaping for a second or 2, so I took him to the vet they did X-rays said his lungs were very clean and they see nothing wrong with him but still gave me this medicine that was like 2 months ago and I still see him tilting his head back and closing eyes after drinking. I now give him water from slightly cracking open a water bottle and dripping it down the leaves next to him because he doesn’t drink unless the waters moving, I spent like 1300 dollars at the vet in just 2 trips with him I can’t afford to go back if you guys have any questions or might know any way to help that would be awesome thanks
