I asked a question about my pup regurgitating too much before but not much has improved since then. If anything, we just got better at limiting it and predicting when she would regurgitate.
An interesting turn of events happened this weekend though. We brought her to the cabin with us (approx. 150 km away) from Thursday to Monday and she didn't regurgitate once. The first time she lapped up a bunch of water after a hike I was just waiting around for it to happen but it never did. When we got home on Monday, she regurgitated within a half hour of being home. Now there's a bunch of variables that changed here but I'm guessing that the biggest is the water source. Our water at home is highly chlorinated from the nearby treatment plant. The water at the cabin is not. We took her same water bowl from home to the cabin so the bowl material was not different.
Has anyone experienced this before? And, is this a likely cause of the issue? There's no difference to me besides taste but I'm a 230 lb (104 kg) man and she's a 3 lb (1.4 kg) puppy. I'm going to try filling her dish with bottled water for the next little bit to see if it changes anything. Any other ideas?
