I love Fluff and Tuff toys, which hold up for quite a while against my moderately destructive dogs. There are no chew proof plush toys, so the five star rating is based on the reality that any plush toy will get destroyed if that is what your dog likes to do. Given that, these are better than anything but the stuff made of old firehoses, which my dogs don't like much. Also, the detailing is always really nice-- these are high quality plush toys you could give to kids, frankly.
This seahorse one is especially good for tug, since it's long and somewhat symetrical and has good grabby bits in various spots. It's a bit bigger than I anticipated. The 65 lb German shep like to carry it around, but the 45 lb coon hound like a smaller toy better.
