Assuming you are joking, of course! Truth is (and as many companion-humans know) companion-canines are very smart, with terriers being among the most intelligent breeds. And I assure you, our three (Jordy, Josey and Wilma) know exactly what is going on. All of them must know hundreds of words--more than they let on. For example . . .
Yesterday, Jordy rolled in something nasty (probably racoon scat). Of course he would have to be bathed (in our barn's shower stall) before going into the house. Nonetheless, since the day was young he stayed outside most of the afternoon. Near day's end, we walked to the barn to feed the horses. He was in the vicinity. We were walking with our backs to him. Without so much as saying anything about what was about to transpire, I perfunctorily asked my spouse "Is there shampoo?" Jordy (who loves water but considers the experience of bathing an indignity) immediately stopped and high-tailed it.
"Shampoo".
