Reputable brand safe non-toxic snuffle mats? Known safe brands? And best mat design?

I’m getting a puppy (age 8 weeks), golden retriever. I want to get snuffle mats for my dog, (for different stages of its life), but I am afraid of most products because I’m scared of how unregulated dog things are. I’m concerned about toxic dyes, for example.

Do you know of brands that have quality control and testing to show they are using safe materials?

And which designs do you find best, throughout your dog’s life? There’s a lot of different designs out there.

I appreciate all advice because I’m nervous about every product I need. I had a dog pass away once due to lack of regulations in pet things so I’m now extremely cautious.

Thanks!
