While many dogs love water and swim like a fish in rivers and lakes, others sink like a stone. It comes down to their physique – dogs with agile bodies, strong legs and a snout that can be held above the tideline swim best. Those breeds with rigid bodies, short legs and squashed faces find the activity difficult. Bulldogs, pugs and basset hounds struggle the most, as they just don't have the build get around comfortably in the water and could drawn, so you'd rather keep an eye if they're next to the pool.
