So I have brought my family up to the lake house my uncles own (Coldwater lake) and rented a PWC to supplement the pontoon my uncle owns. Everything was going well until his puppy showed playfully agressive tendencies towards one of my 3 yr old twins. He nipped her and she's got a bite mark I'm not really worried about, but sitting in the ER habing it checked out after texting a pic to my sister in law who's a doctor. Now my uncle has gone back to his house for fear the dog might snip again, and I also have a 18 month old, so I get his fear. He's not comfortable other people driving his pontoon.. which was our major activity for the weekend. I can't switch the rental to a pontoon because we only have one spot on the dock for a boat, which is already there obviously. The plan was for him to help us watch the kids while we sandwich a kid between us on the pwc. Now there are only 2 of us with three kids. I'm not sure how safe it is for a single adult to hold a 3 year old one pwc by themself.I'm not talking wave jumping or fast speeds, more slow cruising around the lake. Asking for suggestions/advice.
