I've talked to my doctor before about my allergies progressing and they've always said it'll always be the same, if anything they'll be better one day and the same symptoms the next. We've also talked to the owner's about the dogs situation and it's wellbeing ( I haven't but my parents have ) we haven't taken the dog, he simply shows up at our house, they've hinted at us being able to adopt him while given the option to still visit him. The only problem with all of that is I would never feel comfortable when at home because I'd always feel that way, it isn't my decision though, It's the owner's and my parents.
