Hi, welcome and congrats on your new two little babies. I got Louie about 3 weeks ago and went through the same thing so I know how worried you must be. Mine is a finicky eater as well and what has worked for me is giving him boiled chicken (no salt or seasons) with a little broth (from the boiled chicken, not from a can as that has too much salt and preservatives), Louie likes it very brothy which is good so he maintains hydrated when I don't see him drink a lot of water. Have you tried that yet? I put my chicken in the food processor with some of his puppy food and I grind it up to tiny pieces so it's easy for him to eat. Hopefully that will work for you. Also, don't forget to give them their nutrical with their food (it's a vitamin supplement). Good luck and let us know how it works out for you!
