I don’t know about the part that Muslim’s can’t swim, but the part about dogs is true. I can’t understand that myself.
It's a misnomer that Muslims hate dogs. In fact it is a grave sin for a muslim to abuse or torture a dog. And muslims do not eat dogs, even if they live in an Asia country where dogs are on the menu.
Muslims even today still use dogs for hunting, cattle herding, and as guard dogs.
