I'll be interested to see what people say here
My labradoodle - when he was maybe 1? Dove into my cousin's swimming pool after his ball...and promptly freaked out. At first I was like oh well I guess he isn't going to have a problem with getting in the water. LOL.
So anyway - there is a place near where we live called Here Buoy! that I take him to now and our big fat wiener dog goes too. The lady who runs it is fantastic and I'm glad I discovered it. She's got Mal swimming like a fish now and Hershey is getting some great exercise. I was thinking we should take Gambit (our pup) there as well to introduce him to the water and let him get started with a positive experience
