I think my dog knows I didn’t pay much for him

The place I got my dog was a "by donation only" rescue, my therapist had told me getting a cat or dog as an ESA (no access rights) might be good while I wait to be able to get my service dog prospect. I didn’t have much money at that time, but what I had was enough. I picked him out (or he kinda picked us out) and since then.... I think he knows and decided to make up for it. He uses very specific dog toys only, they get shredded in a week but we don't care, he loves them so much. He decided he didn't like his current food, so we spent a ton of money after a week getting several different bags for him to try before we found out he only wants wet or fresh food, and it has to be heated. He is a dachshund mix but requires at least 3-4 hours of playtime daily, as well as sniff walks moat days, and brain puzzle toys. He gets marrow bones weekly, filled kongs, and lick mats. He wears a hoodie pretty constantly now because he doesn't like the cold and has "his" spot on the couch and "his blankets. I love this dog more than life itself, he is worth all the money we have spent and more.
