Need two fluid coolers, but don't have the space? That's the specific problem that Perma-Cool's Maxi-Cool dual-circuit fluid coolers were designed to cure. They combine two coolers in one space-saving, all-aluminum package with a proven fin-and-tube design. They have 1 1/2 in thick cores and 5/8 in. cooling tubes with Perma-Cool's special Turbulator fins to boost cooling efficiency. One of their two circuits can be used for transmission fluid or engine oil, while the other one can be used for engine oil, power-steering fluid, differential fluid, or even fuel. To make them even more effective, some models incorporate integral fans that can move up to 1250 cfm or more of cooling air. This allows you to mount these coolers pretty much wherever you want, including out of the direct airstream, and also can give you cooling protection when the vehicle isn't moving. Hose and installation hardware are sold separately.

Benebone is fantastic for heavy chewers and busy, adolescent pups!
Size: Medium, Style: 4 Pack
This little multi-pack is cost-effective in a few ways, super durable and effective, and I'll definitely be purchasing the multi-pack again. We discovered these about a year ago and have been buying them ever since. I'm just now getting around to reviewing them because they're that good, plus I love that the company is family-owned.
Four "bones" lasts a little over a month for a power chewer, which is a bargain! You get 4 medium size "bones" for the retail price of 2. These smell delicious to dogs but humans can detect the odor, which is so nice. They are incredibly durable, but somehow also not too hard for a power chewer, and they keep pup from chewing on books and other items that we don't wanted chewed to bits. Heavy chewers (and their people!) love these and the variety of shapes means we can swap them out in rotation and keep pup's interest going for a few weeks.
Wait until your pup has all of their adult teeth, as they are a little too hard for teething. And for super power chewers, watch out for the fish shaped chew, as this one seems to allow larger pieces to be chewed off the fish head "corners" more easily due to the relative thinness of the shape at that point when compared to the other 3 shapes.
Keep an eye on how much your power chewer is taking off of these "bones" (little tiny pieces do get chewed off) and toss them (or recycle with Benebone!) when your dog is able to chew off more than a crumb size piece.
Hooray for Benebone! Hooray for family-owned businesses! We'll be back for more!

Seems Very Durable So Far
Size: Small, Style: 4 Pack
My dogs are really enjoying these chew toys! These keep them busy for hours!! So far they seem very durable and my little dogs can really chew and destroy so I’m happy about these so far! They rarely each chew a toy at the same time, but choose to take turns instead. But now they each have a chew toy and they are happy campers!!

Recommended by my breeder
Size: Small, Style: Wishbone/Dental
Purchased these two small sized Benebones for my puppy Springer Spaniel. It’s one of her favorite toys and it is well used and well worn. Replaced these with the medium size recently as she’s almost full grown now.

Our All-Time Favorite Chew Toy
My Dog's FAVORITE chew toy. It lasts so long. I love the bright color and the durable silicone. She can chew this thing forever without breaking pieces off of it. I finally bought her a new one because I felt like she had the other one longer than is probably sanitary, not because it was unchewable or damaged. Please don't ever stop making these Nerf Dog Bones.
