I missed your post - I think the best way to bulk Mathilde up would be to add the 1lb of meat to her buscuit, it really does help to body them up. Another thing you can feed her is raw chicken wings, do not cook them as the bones become brittle if cooked, the bones are hollow and soft if raw but 3 0r 4 a day will build her up. You will be surprised by how much, you may need to cut the bisuit back to make room for the meat but very quickly she will pile on weight. I buy the Tesco value chicken wings about £1.50 for a pack of 18 and once they get the taste for them they love them.
As for seasons if she is on time you should be OK but the kennels should be set up to cope with an in season bitch, speak to them if your worried Ann.
