99 Prerunner Seat covers and shocks

I've been sorting out a 99 Prerunner recently purchased. Interested in a few things, wanted opinions on a decent front bucket seat cover, and shocks, since the truck actually belongs to my dog, and I chauffeur him around.

Looking for a slipover waterproof cover for the front buckets, and will need to replace shocks and struts soon. So the truck will be stock height, and I'm 67, so just looking for a good set of shocks for highway and light useage on gravel roads and the alfalfa fields and sagebrush, in eastern Oregon.

Also, the rear fender flares and the trailing edge of the rear wheel openings were damaged, maybe the tires chains came off. My front flares are decent, but the rears will probably need to be aftermarket, that will cover the damage. I see a few outlandich big ones, but I will be staying with the 31-10:50-15s.

I tried searching the past forum posts first, looking fo advice.

Any thoughts are welcome, thanks!
