Thank you for welcoming me

Ok so most are going with dry feed there at all times for her to help herself? Im trying to get toilet training done so with the 3 meals I was hoping that would be better for timing her.....but she seems to just do it whenever!! lol. Defo not half hour to an hour after...
This morning after going to pee she only ate a couple of mouthfuls & is asleep again now...She is only 1.7kg so Id imagine she doesnt fit much in her wee tummy!
Breeder was feeding pedigree pouches & bakers purina dry food, I have since read up on it though & it doeasnt seem to be a great choice! The vet gave me a bag of dry which I take it they suggest its the best one to have, I didnt ask as had too many questions for the time we had!
Thanks again & soz this is a bit long winded!! Karen.xx
