Nutritional? Not in the slightest. Helpful for training? Yeah. I used these for my Roborovski hamster actually instead of a rabbit. I had to smash it into small enough pieces for him but when I did, he absolutely loved them. It helped in training him to be used to be in human hands.
Great look to this one but since it is engraving on black, the text starts off being difficult to read and then becomes even more so with wear and tear even with protective layer. Good amount of space for information though.
Great product - really gets at the undercoat of my Labrador who grows a heavy one in the winter. You just have to be wary of how much brushing you give since the dog's skin can be agitated with too much. That's with any product though. This one really gets through the coat and brings out much more loose hair than other brushes.
My dog still pulls during walks (even after so many years...) BUT this harness helps make the pulling not so bad. He's quickly and easily corrected by this harness since it falls across his shoulders. He's still able to get some leeway though and has fallen out of the harness a few times but overall, good product.
For the longest time, my parents would feed my dog this because it was a cheap option that they could buy in bulk. There's a reason for this - subpar ingredients! He would have chronic health issues growing up including dry skin, hot spots, and wavering weight loss and gain. Once I took over his care, I switched him to a grain-free, all-natural dog food and now he is loads, loads better. I don't really see this having the nutritional value an active Labrador needs.
There are several sizes for this product - I ended up purchasing the 3" one a few years ago when I had a Roborovski hamster. Those guys are tiny little critters and that was the smallest I could go. The ball served its purpose in keeping him running but the locking mechanism wasn't also secure. I did go through probably three of these. Every once in a while, if he ran a certain way, it would come loose and you can imagine how hard it is to catch a 1.5" hamster that has escaped! It also collects a lot of dust so must be cleaned after every use. Maybe it's less troublesome for a less active hamster type?
I actually didn't own a chinchilla but had a Roborovski hamster which I wanted to give the opportunity to have sand baths. I used this container to lay down his sand and he loved having the spacious area to roll around in. Sturdy product and very easy to clean.
