So I just got a call from my roommate saying my dog got into this abandoned â€œwater gardenâ€ in the backyard. She isn't too sure how long he was in it. Itâ€™s full of scum and really old stagnant water. Is there anything I can do to hopefully minimize any sicknessâ€¦Iâ€™m brining him to a friends cottage this weekend so the runs would not be good!! (not to mention I don't want him feeling sick!) Thank you!
