Questions/Tips about my new girl ❤️

Hello guys! I recently bought a girl from my friend but I’m just wondering is she a doodle? The reason I’m asking is because he got her from some man selling them for pretty cheap lol $400. Don’t really care if she is or not but just curious! Thanks in advance :)

Also taking any tips and what I should know about grooming, excercise, diet ect please!
