Absolutely, take him with you! At the very least it's a great way to introduce him to the water, but let him go at his own pace. He may just want to put his feet in and drink, then again, be prepared if he wants to do more...If he's comfortable in the water, if you take a few of his toys with you, that's a great way to teach him how to "fetch" as well...Tennis balls work well too.
Some boxers love the water, some don't. Buck was my water baby, learned to swim at 10 wks and never looked back. If someone was in the pool, so was he.. I have a ton of pics that I need to get scanned & you can see how much he loved it. Now Tia, hated the pool, but loved sprinklers...Hmmmmm...Samson will go into the creek, only if you get in with him, he'll take a quick dip, then he's done....Angel, well the jury is still out on her.... :lol:
