Thank you gift for BIL

I recently brought home an 8 week old puppy. About a week later I was rushed into emergency life saving surgery and had a week long stay at the hospital. Due to all of this and the estimated 4-6 week recovery I communicated to my family that I needed help with the puppy. My brother in law stepped up! He flew to the state I live in and picked her up, took her back to his place and has been going through all the puppy things-potty training, etc. what a blessing! I’m trying to figure out how I can say thank you with a really nice gift. My BIL has $$$$ and wants for nothing. Help with ideas!!! Budget <$3000
