Sharp Flower Hand

Okay my dog is a short haired pom pom that always takes my shovel while I'm digging holes. I'm trying to make a flower garden and in order to do that I must dig holes to put seeds in so while my dogs are playing I usually start working on my garden then my pom pom comes and takes the shovel ( a hand shovel )that I use away and when she carries it it sounds like it hurts but the shovel isn't really sharp it's dull and then were I tried to dig a hole she comes and starts digging so why does she do this? Does she hate the shovel? What does it mean?!?
She already has a mommy and owner my mother
Also she just fell alsleep and the tip of her tongue is sticking out the front of her mouth why does she do this
