I have a dog that I rescued six years ago and a six month old bitch also rescued from the street very young.
The problem I have with the puppy, not eating enough or none at all, the vet said she is healthy and good condition and not to worry about her, which is easier said than done in my case. He suggested feeding her different puppy food that are in the market but that didn't work unless I hand fed her.
I consulted a professional dog trainer, and like some of you said, he suggested to put the food down and to wait, and as soon she moves away, to remove the bowl and not to give her the food back until dinner time or breakfast as the case may be.
I eat before my dogs, I don't feed them scraps, they get all the exercise they need, what's more they keep me in shape.
However, all said, I worry terribly when she goes four or five days without eating, and so I give in and start hand feeding again and so the vicious cycle starts again for a couple of weeks until I'm confident she has replenished her puppy fat again.
I would appreciate if any of you reading my plight, can give me a more permanent solution to my problem.
