Previously I wrote about the ability of certain parasites to develop resistance to the various drugs we have been using to combat them. These articles have primarily been directed towards fleas and ticks. The “resistance factor” can also be applied to other parasites that afflict our pets, such as Heartworms, Hookworms, Whipworms, etc. In horses, the practice of alternating deworming products has been in existence for over 50 years. This is to prevent the parasites from developing a resistance or immunity to the product. Another factor to consider is the pets weight. In the past the products given were for weight ranges, such as 1-25 lbs., 26-50 lbs., and 51-100 lbs., etc. Some dogs have reacted to the product if they are in the lower sector of a range. For instance, if your dog weighs 8 lbs. the product prescribed often is for dogs that can weight 3 times that amount. Now that has a ll changed. Veterinarians now have the opportunity to customize the ingredients and individualize the products dose for your pets exact weight. I believe this is the ideal way to protect your pet. It is very safe and has been tested for several years in other parts of the country. This program is called: “Custom Parasite Protection” (CPP). The program customizes the ingredients of the product for your specific dog. It is shipped directly to your home with your pets name and weight on the product at no additional charge, or it can be picked up at the veterinarians office. The protection provided also is greater than other products as it not only protects against heartworms, but roundworms, hookworms, whipworms, and tapeworms. It also eliminates the breeding capabilities of fleas and thus aids in flea control. The product comes in a flavored chewable pill or a flavored liquid and is given 1 x each month.
