hello,, its my first time on the site today so got a few questions really,

i decided recently to breed from my boxer martha and had sucess twice on the 11 and 13 day into her season, iv read that you wont really tell untill 5/6 week properly its been 2.5 weeks and she has calmed down alot as she has a crazy temprement usually she is mad never sits still, but after her first season she chilled for a few weeks after but then went back to normal so not sure if this is a sign of pregnancy will have to wait a bit longer i think.
My main question is, she is a skinny dog which i know is the boxer build but she should carry more weight than she does i personally think and althou she does eat ok as long as my other two are in the room she hasn't the biggest appitite (not for food anyhow) but if she is pregnant shall i feed her more or an extra meal? i worry that she is a bit to skinny to carry healthily! also is there a rough amount of puppies to a breed (obviously not in all case's) and last but not least does her excersize routine have to change as she mental on a walk she bounces every where!! thanks for reading abi
