I have a two week old (as of tomorrow) dachshund puppy that has only gained an ounce since birth. She was delivered c-section and weighed in at 5.3 and at one point I was able to get her up to 6.8 and for the past week she has been holding at 6.0 sometimes a bit less. I feed her ever hour only once during the night. She is sucking off of mom as well, but her suck on mom seems to be weak. There were three pups born in the litter one did not make it and the other one that did, is huge he was born a 9.3 so he is up and well on his way. She has been sucking off my pinky I dribble milk on it. I tried a bottle but she drinks so vigorously, she aspirated I rushed her o the vet and she is now on amoicixilian. I have never tube fed, and would be afraid to but if someone could tell me that they think this may put weight on her I will try to find someone that can help me and we will move in that direction. Currently when feeding her (Esbilac) every hour I go thru (4) 3ml syringes, and by the time she is done her tummy is round. I burp her and generally can get some type of burp out of her. I am thinking there is something more going on here, I read about the Portosystemic Shunt (PSS) and wondered if she could have this? Any advice and help would be greatly appreciated. Help me keep this little angel alive... Thank you all so much..
