I have a pool but don't let Jaden or Jewelina in it. It's rather large and goes up to 12 feet on the deep end and I'm always worried if I get them in the habbit of jumping in the pool if they ever get out of the house somehow without my knowing it, I'm afraid they'd jump in and because they love water so much and because they are so small they can't get up the sides so whenever they go near the pool like they are going to get in the water they get a firm "No" from me. I do have a kiddie pool I keep on my back porch in the summer and I let them get in that and swim and they have the best time! I've not had any problems with their hair at all and I think Mojo is a silk coat as well? So I don't think he'll have any problems at all!
I bet he's going to have a blast being in the pool with you this summer! Take loads of pictures for us!
