Won't be a customer for this product...we have three German Shepherds..too much work...and they will swallow them up in a microsecond.
I will, however, give you an idea for another product. Don't know if it has an audience, but it is along the lines of what you are doing.
When large dogs are small you can buy pre-made treats and they'll spend a good amount of time working on them. Past a certain age/size they'll instantly crack them into pieces and it's the end of the story.
It would be interesting to have healthy protein-based edible treats of different sizes (2 to 12 inches?) that are hard or resilient enough to keep a dog busy for a while while they grind away while providing nutritional treat.
One of the options for dogs like ours seems to be to buy cooked bones like this one:
They will work on something like this for days. The problem is that they are not really nutritious and they will eventually fracture them and they will splinter. The dogs won't get hurt but it's always of concern having bone fragments on the floor. Also, I don't think you necessarily need something that will last weeks. If it's good for a day or a few days (depending on cost) it's probably OK.
Read the ingredients and think about whether or not dogs evolved to eat this stuff. I don't think so. They can get sick and have intestinal problems from these kinds of treats.
Also, read some of the comments on that particular product for a view into what I am generally talking about.
I hadn't thought of it before, but when our horses get their feet trimmed, the dogs (a 100lb Shepherd and a smaller Shepherd mix) love to gnaw on the trimmings. Hoof trimmings are basically really thick fingernails.
They'll gnaw on them for hours. Wonder if there would be a market for it.
Dogs will eat anything. One of my GSD's almost died after eating about a third of a blanket. His xray looked down-right scary, with this ball in his stomach. We were very close to having to have surgery to cut him open to remove it (which would have been very dangerous and very expensive). Somehow he managed to vomit the thing out in large chunks. We all dodged a bullet on that one.
So, yeah, it doesn't surprise me that they would eat horse hoof trimmings.
If you were to productize something like that you'd have to make sure you run through some testing to ensure dogs won't be harmed. The product liability element in products that people and pets eat should not be ignored, particularly in a litigious society like the US.
