my dog is not really able to wag his tail. he is the happiest dog in the world and pretty much never stops waging his tail. but today he started walking a little funny and his tail like kinda lumps out from his but. i got close to him and started rubbing his ears and sayin his name in a really calm and happy voice and it doesnt move. BEFORE you say take him to the vet, im in germany and nothing is open on sunday. so i just wanted to know if anyone else has had a dog that acts like this, im gettin worried about him.
