I have had to bottle feed my singleton puppy since mom had no milk. I am having a lot of problems finding the right nipple and bottle. Some nipples are not fast enough and some come out too fast. He is 2 weeks old now and is a maniac when nursing and sometimes gets some in his lungs and makes those garling sounds. Can anyone give me an idea that worked for you?? 1 more week and I can start the gruel feeding. I have 3 Bulldogs but this one is a Mastiff baby.
