Having the same size dogs as you, I would say that the majority of teats I have found, are just not suitable. And I must have tried about every hand rearing jobby on the market!
The most successful for my tiny tots came from PAH and is cheap. It's made by Sherley's and is in a green box. The teats are the best I have ever found for tiny little mouths.
I believe thay only cost me a couple of quid. I was so pleased that I went out and bought 3 more boxes, just in case I needed extra teats. And so I could have bottles in the steriliser.
I won't tube feed mine either, they are so tiny that vets worry in case they get it in the lungs.
I have my fingers crossed for your girl. Sending you positive vibes. Jean
