No I'd do a 2 or even a 5 speed. That one might work for a simple poodle but thick like a doodle it probably wouldn't work well or last long. I honestly recommend a 5 speed as it can cut through thick hair like butter. https://www.amazon.com/Andis-Pro-Animal-5-Speed-Detachable-Clipper/dp/B00J0GOC1I/ref=mp_s_a_1_3?crid=1CDT9GIY3R9Q2&keywords=andis+5+speed+clippers+dog+grooming&qid=1669087381&sprefix=andis+5+%2Caps%2C296&sr=8-3
Also you'd have to wash and fully power dry the dog before you do haircuts. Dirty hair clogs up the blades.
