Enthusiastic Chewer Approved
Color: 2PC-Bacon-Green, Color: 2PC-Bacon-Green
You would think that a two pack of chew toys would be a great option for a household with two aggressive chewers but the dogs still fight over the toys. They seem to really love them an are choosing these first among several tough chew toy options.
I can't speak to whether there is a bacon flavor but they did seem to have a slightly smoky smell to them when they arrived.
The girls have been working hard on them for about a week and while they certainly show teeth marks, they appear to be holding up well. The size is nice for medium to large dogs and the shape lets them hold on to it while getting an angle at the apple knobs on the opposite end.
The only downside, if I had to name one, is that they are heavy and if (when) your bestie drops the toy on your bare foot, it smarts.

Tough Toys That Keep My Dogs Busy
Color: 2PC-Bacon-Green
I cannot personally confirm the bacon flavor because I am definitely not going to taste these myself, and I did not notice any bacon smell when I opened the package. That said, my dogs seemed interested in them right away, so whatever scent or flavor they contain appears to be appealing enough for canine approval.
What impressed me most was the durability. These toys are much tougher than many chew toys I have purchased in the past and have held up well to regular chewing. My dogs enjoy carrying them around, chewing on them, and staying occupied with them for extended periods.
The size works well for medium to large dogs, and the material feels sturdy without being excessively heavy. While no toy is truly indestructible, these seem capable of handling some serious chewing.
For the price, getting two durable chew toys is a good value. If you have dogs that enjoy chewing and need something a little tougher than the average toy, these are worth considering.

Great tough toy!
Color: 2PC-Bacon-Green, Color: 2PC-Bacon-Green
Finally, a dog toy that my bully cannot tear up! They do have a questionable appearance, but we won’t discuss that. Other than that, she does really enjoy chewing on them, carrying them around, playing with them, all things! They are really well-made. I don’t have to worry about little pieces breaking off and the fear of her swallowing any of it. They have held up really well. I also love that this is a two pack so if she does lose one in the yard or leaves one outside, she has a backup one that’s available for her inside. The size is really good for medium to large size dog.

My dogs love these!
Color: 2PC-Bacon-Green, Color: 2PC-Bacon-Green
My dog love to chew on bones. So, I thought why not? I will give these a try. My dogs (olde english bulldog and french bulldog) love these. I love that it came w/ 2 bones so they aren’t fighting over them. They are both different colors. The ends are shaped as apples and the middle is leaves and tree limbs. They are pretty hard. They are supposedly bacon flavored but they have no smell to them. They are supposedly for aggressive chewers. They seem well made but my dogs will put that to test as time goes by. Since it came with 2 bones I feel like the price point was decent. It’s hard to find toys/bones that my dogs like so when I seen them chewing on these it made my heart happy. They are bulldog approved by my 2 crazies.

Finally, a treat that lasts and doesn’t make your house a mess!
Color: 2PC-Bacon-Green, Color: 2PC-Bacon-Green
These are fun, nylon dog toys. They actually have a smell to them that is noticeable if you put your nose right up to it. Our dogs love, beef knuckles, and they make such a mess in our house that we needed an alternative. I am happy to report that these worked! They also have several knobs on them so the dogs can wrestle with them a little bit. The way they are shaped makes it very easy for the dogs to pick up especially when you have short nose dogs like we do. The price for these is much better than what you would pay in any store. I think these are a great bargain and a great way to treat your dog without wrecking your carpets! You can also throw it in the dishwasher if you want to. I definitely recommend!
