Hello Celes, There is a something called the packing order amongst dogs. there is one alpha dog and the allothers fall below this dog. It looks like the alpha dog is the male pom. But YOU have to prove to the male pom that he is not the alpha dog, but in reality YOU are the alpha dog. you have to prove to him that you are the leader of the pack and and what you say is the final way, and the pom must learn to accept and respect that. And one of your orders are to mek the pom know that biting the lab is just not acceptable.
About the pups digging holes, remeber that all pups are playfull. It is abvolutely normal for pups to dig holes. But since it a cause for human safety, try redirecting thier energy onto something else. If you hve a garden try tying a piece of thin rope and some toy at the end of the rope. Tie the upper end to something high so that the end with the toy just hangs (from the ground) about the headheight of the pups. The pups will enjoy pulling and and biting the toy andhoepfully wont look at digging.
Soaking the paper in urine and keeping it in the gareden works!!!! After the pups had thier feed or water to drink take them in the gardeon near this paper (preferably ona leash and dont move till they pee. 6/7 times of this will have them peeing around the paper. Remember consistency is the majic word.
My wife has a wonderfull way of giving medication to the dogs. She crushes the pill, mixes it with 5 ml of water and uses a syringe (without the needle). She draws the mixture in the syringe and opens the side of the mouth and squeeze. Keep the dogs mouth closed after sqeezing syringe, till he has swollowed all 5ml.
