Good Product But I Need Something Indestructible
These were advertised for aggressive chews, but my 2 mini schnauzers puppies quickly bit off the little prongs within an hour. I didn't put food inside them; I just wanted them for chew toys. Well, they were not hard enough for them. The size was perfect for puppies, but they were not durable enough for my 'heavy' chewers. I hate I can't find chew toys they can't destroy! Now they bring in sticks and mess the house up.

Works great with toothpaste.
They lasted longer than most toys but eventually my dog was able to tear them up.

We have three of these (one for each dog)
My dogs love these. I don’t put any paste in them. I stuff them with their dinner kibbles and then use something like peanut butter or bread on the ends to keep the kibbles in for a bit while they toss these and roll them around. Keeps them quite busy for a long time AND the best part is I have had 1 for months (and bought more) but this toy has stood up to hard chewing for as long as we’ve had them.
