Cinnamon - so sorry to hear about your dog
. We've lost three dogs in my family in the last 6 months. Each time, another puppy has been in situ within a week or so. When my sister's dog was pts, her dh wanted to go and get a puppy the following day and she arrived a week later. Dsis wasn't keen because she felt so disloyal to their old dog. My mum, who thought it was too soon when my dsis got her pup, had to have her dog pts in feb and she'd got her new puppy within a week also
. I think that having a puppy is definitely a good distraction and your old dog will never be forgotten. BIL's parents had got their new one the day they had their dog pts (they'd actually been to look at her a few hours before their dog was pts).
My BIL wanted their new puppy to come straight away so she could still smell the old dog in their house.
Sorry for the ramble, just wanted to say that it's quite common to want to have new dog when you've lost one (even if it does feel a bit strange).
Re MFP. I haven't filled it in for a few days because we've been away. I was reasonably good in that I didn't snack constantly. However, I don't think the things I did eat were particularly great 
.
We got home Sunday night so should have got straight back on it yesterday but ate far worse yesterday than I have since I started
.
Today, I am going to do better!! I weighed myself this morning and I've put 2lb on so need to really get a grip if I'm going to fit into the dress I've bought for a wedding next month (not my own wedding
!!). I can get the dress on and just about do it up but it is tight around my middle. I think if I lose another half a stone it should be fine, right?
