Bozita is not a low protein diet.
Any moist/wet food is at least 75% water, so to get to the actual protein level in the product you multiply the protein percentage by 4. The actual protein in Bozita is at least 40%, assuming from the link above the stated protein on the can is 10%.
I would rely on your vet in terms of whether or not a low protein diet will help or not.
