my dog is pregnant is it getting close?

Question
Hello my dog is pregnant and I have no dates to go off of. I know she is huge. I know she has milk in now. To me she seems to be breathing heavier then usual. She is eating everything she possibly can. She is acting like she is starving. I haven't gone through this before so I don't know what to expect or look for. I have made her a bed with lots of blankets so that way she is comfortable for when it is that time. I hate to leave her if it is getting close. I know it would help if I knew when she did get pregnant but I don't know. If anyone could help out as to if its getting close or if we still have some time. Thanks :)

Hi Kim

You want to make sure you're not feeding her too much and not too much puppy food.  Her pups will grow big and it can cause complication in whelp.   

You can start monitoring her rectal temperature.  Also when she starts nesting and panting more, you can take that as a sign.    

Good luck.
