Dog bit my hand first thing this morning....

Virginia
So my boyfriend Grandma's dog got into my son's toys last night. We have them put away so she can't get to them but somehow got in them. I saw it laying away from her and I tried to grab it. She was asleep on the couch while it was on the floor. She jumped up and bite down on my hand as I tried to put it away. She didn't cut any skin but God she squeezed it. I yanked my hand out and yelled to tell Mawmaw what happen. The dog tried to bite Mawmaw but she was quicker and put her in the cage. Ever since then my contractions have picked up. I'm on procardia already to stop the contractions but it's not working as well as it should. I'm debating on calling my doctor to see if I should come in being 4 cm already or try to calm them down myself. My hand is just swollen and sore. This dog has already hurt my son three times and now me and Mawmaw too...She is going...
