Human hair is usually about 4.5 to 5.0 pH. Dogs' skin tends to be neutral (about 7.0 pH) to slightly alkaline (8.0 pH).
Not all shampoos made for humans are formulated with the same pH. Some may be quite acidic, as low as 2.0 pH, and some are as alkaline as 9.0. Most are around 5.5 to 6.0 pH. Dog shampoos also vary in pH, although usually dog shampoos are slightly more alkaline, ranging from about 4.5 to 9.0 pH.
I think you should buy that dog its own shampoo 
It is not a great enough difference in pH to do any damage. You can use human shampoo on a dog who does not have ultra sensitive skin. pH in humans and dogs vary greatly depending on what you ate that day, temperature, hair color, etc. People and dogs do not have one constant pH level.

I plagarized
Dogs skin ph is 6.8. people skin is 5.8.
All dogs have hair some people call it hair some call it fur.
I learned the correct shampoos and proper bathing procedures in Grooming school. If this is for the same project that you were talking about yesterday than I suggest you go to some local grooming shops and speak to them.
If you insist on using human shampoo than at the very least dilute it half and half.
