Extremely anxious about bootcamp?

I have just been told after a year and a half battle with the OOM and MEPS about getting into the Navy, that as soon as I pass my last doc test, which is inevitable, I will be taken to MEPS and pick job and time to leave. This is not a problem, but what I am anxious about is running. I know it sounds silly since I am more than physically fit, but I am really scared about it. Maybe it is because I am not a runner by nature, and this entire year and a half I have spent changing everything about myself to make it better and stronger; but then again, it could be that I have had to wait so long. Could anyone with a lot of knowledge about Navy bootcamp give me some insight as to what to expect? My recruiter has told me very little. I hear from some that the "running is pathetic and you rarely do it in boot" but then I have heard from a recent grad's wife that he ran all the time. I am just getting mixed answers and I don't want to be stunned when I get there all amped up and ready to run and then have an adrenaline drop because we don't run or swim. Just some insight as to what I have to be looking forward to would be fantastic.

I also am anxious about leaving my dog, who is my child basically. I know that I must leave him throughout boot, but how long must I wait until the military puts me in the position to take him with me? Please no smart answers, I just am asking because he is important to me. Thank you.

Thank you in advance for any helpful answers!
