Do Canines need vegetation?

​Unlike felines who are obligate carnivores, canines are omnivorous scavengers, now to me that says everything!
I believe canines do need vegetation even though some argue that they do not, or that they don’t break it down well, which there are ways around that…
…I’m sure almost every dog owner by now has seen their dog pick at a blade of grass or two, which that alone says that it serves a purpose. I believe vegetation at the appropriate quantities can be very beneficial for dogs, especially herbs whether dry or fresh, especially if they not have access to it at their own will. For instance, I love giving my dogs cucumbers from my garden in the summer time as it is very cooling and has liver decongestant properties as well, plus a great way to add more hydration into their food, now if I were to give it to them whole, chances are that it would pass right through them, and make it a challenge for their bodies to process. Hence, I either finely mince it or I make it into a puree and add it to their food mixed in. We can definitely do things to make it easier for their bodies to digest vegetation such as steaming spinach, kale, broccoli, cauliflower, etc. Studies show that vegetation in a carnivores digestive tract builds their microbiome, when in fact meat alone does not build the microbiome.
 
In the fall, I like to add things like pumpkin and squash as a puree base as well for added minerals such as magnesium, potassium and vitamin A, why?
If you notice the trend that I’m going with here is that I tend to follow the seasons and look to nature as my guide to nutrition, whatever is in season is what I tend to go for- both for me and for them! Studies show that produce grown during it’s ideal growing period contains more nutrients than when grown out of season. Now is there anything wrong with feeding pumpkin in the summer time?- certainly not! But I like to give my pets a break from certain foods, and as I do that, something else comes into season!
