So I went out and bought organic cranberry pills that say no color, sweeteners, preservatives, starch, milk, lactose, soy, gluten, wheat, yeast, or fish In them. They are 475 mg per pill so how many do I give Lola who is between 45 and 50 lbs and Lucy who is 12 to 15 lbs? or do I give them both the same amount? Is says on the bottle for adults to take 4 a day but that seems like a lot for dogs! Thank you!
