Dogs can eat paneer and ghee, but it is not recommended to feed to them on a regular basis. Paneer, ghee, and other dairy products can be difficult for dogs to digest and cause stomach upset and other digestive issues. In addition, paneer and ghee are high in fat and calories, which can lead to weight gain and other health problems if fed to dogs in large quantities.

Yes you can give paneer (small quantity as topping over food) n egg white (1) as a treat to 3 months old puppy. I used to give. Not very much sure about ghee (never tried) but other experts can comment on it.

Don't give ghee it is not good for stomach
