Table scraps are good for one thing....ending up at the vet. My Dh would love to feed Rosie table scraps until she got so sick. It costs us $400 at the vet. Table scraps are against the law at my house now.
Rosie has always been a picky eater too. I was told to put a little chicken broth on the food to get them to eat it. But I was afraid to do it because I thought she would get used to eating it with the broth. I did mix some wet with it and it made her more interested in it. I ended up trying to find one she liked by getting samples. Many places offer the samples. Now I just home cook for her. Since I started the home cooking she doesn't beg at all. I don't know, maybe she is more satisfied?
I would try some samples and whatever you do, don't give in on the table scraps. Hopefully the begging will stop.
