I have read that due to their top heavy build and short legs there isn’t enough “pedal to the metal”.
Because I was concerned about this matter, I sent my former boys, Duncan and Murphy to canine swim camp…LOL true! It was for boarding while I was away. They used life jackets all of the time at the school. It was a salt water pool. Afterward I always took them in the pool, lake, river whatever with their life jackets on. They always loved it too. But neither could swim without the jacket. We tried and tried.
Thanks for this. Mine are quite wary of big expanses of water and seem to know when it’s too deep to enter. They have a canny knack of finding little streams to paddle in though, but hate having to be put in a little baby bath for washing down after a walk.
