Since you are thinking of switching foods, I recommend raw diet as thatās best for them now and long term.
Thatās easier to rotate proteins to prevent new food allergies from coming up.
Dogs need moisture in their diet, raw is around 70% moisture, kibble(even the good ones) are less than 10% moisture!
Thatās why all kibble dehydrates them, even if they drink 4 cups of water with each meal, the moisture and everything is pulled from the kidneys even when water is added to dry food. That causes constant dehydration and causes Kidney and liver disease(my 2 other dogs that were kibble fed, are now have Kidney disease and they were given 6 months at most to live after being diagnosed)-they are on raw diet, low in phosphorus and sodium and itās been 13 months since they have been diagnosed and we just got their bloodwork and urine checked, their kidneys are working great, even though they still have kidney disease, their kidney bloodwork and urine check have not been this good-itās all in the normal range for BOTH of them!
Rotate proteins prevent food allergies(my dog recently developed an allergy to the food he is eating every day)- i didnāt know that rotate foods and proteins prevents food allergies until I did my nutrition courses for dogs, and people were coming to the pet store I work at with food allergies and kidney disease(every day at least 1 person comes in with food allergy from no variety).
I can give you recommendations on the great high end kibbles if you canāt feed raw.
Iām happy to help
