I have a one year old female shit su and I need to buy her hear worm chewable tablets, are they all the same? Do I need a vets prescription, What is the best one for her?
Also, I would like to know what is the correct amount of food she should take every day and if it is ok for her to eat fruits like apples, oranges and grapes.
Yes you need a rx for heartworm prevention. I usually recommend a cup of food per 20 pds 2 x daily but this could change depending on the amount of calories in the food. Some fruit is ok. vetcare
