[Seeking Recommendations] Pet Reburial Services

TL;DR: Childhood dog is buried in backyard and property is being sold, looking for recommendations, please and thanks!

Apologies if not the right place (wasn't sure if this counted as a classified ad or not), and I realize it's a tad morbid. However I learned today that my parents intend to sell their home for the last 23 years. About 5-6ish years ago, my dad buried my childhood dog in the backyard when he passed of old age.

It's tearing me up at the thought of leaving my old buddy behind like that. I'd dig him up myself, and probably will if it comes to it, but I'm aware that exhumation of decomposed pets, even if it's just bones, is probably best left to pros.

Does anyone have a recommendation for a pet exhumation service that provides services in North Houston/North Harris County? The decision to move is final, but no dates are set, so it's nothing urgent.
