Can you use "people" shampoo on puppies?
I used my own shampoo on my adult dog once, and never again. It cost me an expensive vet bill after she was allergic and her hair came out in handfuls. She had to go on steroids and they said NEVER use people shampoo on any animal...way too strong for their skin.
If you don't have any pet shampoo but very much need to clean your pet asap, dish soap is your best bet. Gets them clean and doesn't strip their fur of oils they need.
Dawn is often used on animals infested with fleas. But I wouldn't recommend it as a regular cleaner for animals!
I usually use baby shampoo on my dogs. Doesn't burn their eyes and doesn't strip the oils out of their fur. Of course, my dogs are minpins so they don't get bathed very often. I now also own another dog (sheltie/border collie mix) so I will be bathing him more often.
I like to use Puppy Tears by Kelco, most likely you would need to order online.
I also like Filthy Animal by Kelco it is a all natural flea and tick prevention helper.
I also use diluted Dawn especially for greasy ears.
