Puppies don't require a lot of baths.... coz some times a dog can catch a cold... well, especially long haired ones coz they need to be dried using a blower coz of their thick fur. Just bath once in 2 weeks is sufficient. If the pup smells, it could be the ears or the mouth. Then you clean the ears... mouth should be the smell of food.

You can get hold of some dry shampoo, powdered form and has some perfumed scent. I think it's made using corn starch or some organic powder that doesn't hurt the dog or cause irritation. Just apply some of the powder, massage it into the fur and brush your pup, will smell nice and fresh.

Condense milk is a big no no.... well, for certain is some got high sugar content.... another is the lactose from cows... best to use those made specially for animal consumption. You can try and get hold of goat's milk. Perfectly good to feed goat's milk.
