It may just be playing around, but I'm not exactly sure.
He is obviously scared. When a dog holds a tail behind its legs then it is scared.
run away with their tails between their legs
Red pandas usually move around on all fours unless they're feeling threatened. When they are feeling threatened they stand up on their hind legs and let out screeches and hissing sounds.
tarantulas hiss when they feel threatened, and usually put their front legs in the air while they do it. This is to make themselves look larger so that they do not get eaten by whatever scared them.
Because hes scared
Yes, it is scared that he will have an operation too.
they might like each other!! It's part of how they communicate. Gerbils thump their legs when they are feeling threatened, scared, annoyed or being territorial. They also do it to warn other gerbils of food, predators or to tell them to go away. I have also find that they do it when excited because when I bring apple of toilet roll (their favourite things) they thump their legs out of excitement. Basically it is to show any extreme emotions they may be feeling to each other and you.
They usually keep them between their legs when they're depressed or scared.
yes. all dogs do this is perfectly normal DO NOT DISCOURAGE THIS ACTION
to show how they feel. if its tucked in between its legs then its scared or unhappy. if its wagging then its exited or pleased.
Well they use it to wag it back and forth. Also dogs use their tail to show the people arround them how they are feeling. If the tail is wagging in a quick motion back and forth the dog is happy. When the dogs tail is between their legs it means they are scared or afraid.
