Formula M.A.S.S. Weight Gainer is great for athletic canines to increase and maintain weight, muscle mass, energy levels, reduce fatigue, fuel muscle during performance, and enhance recovery time. By increasing a healthy calorie intake with a daily exercise program your canine will build more muscle to amplify strength. Show dogs, hunting dogs, agility dogs, working dogs, weight pulling dogs, abused or neglected dogs, recovering or nursing mothers, puppies, and even your pet at home will benefit from using Formula M.A.S.S. Weight Gainer.

Formula M.A.S.S. Weight Gainer offers an excellent source of premium quality vegetable fats. Fats are concentrated forms of energy, and contain two-and-one-fourth times the energy as an equivalent weight of protein or carbohydrates. Since fats are abundantly available in both plants and animals, they are an economical source of productive energy and fatty acids. Fats also carry fat soluble vitamins. It is extremely important to feed your canine premium quality fats since they can influence the ability to perform muscular work, skin, and coat condition. Puppies that are not fed adequate amounts of fat can have developmental problems and growth deformities as well. Our formula offers the right balance of premium quality vegetable fats to help your canine live a long and healthier lifestyle.

Formula M.A.S.S. Weight Gainer contains high quality protein. It is important to feed your canine a high quality protein to promote a long and healthier life. Proteins are broken down into separate amino acids in the digestive tract by the action of enzymes. The liver then processes the amino acids into protein that the body needs to build muscle. When there is an imbalance or efficiency of animal protein in your canines diet a variety of health issues may occur. Epilepsy and seizure disorders are among this list of health issues. Proteins/amino acids serve as important building blocks for body tissue, organs, enzymes, hormones, and antibodies which are important for adult and growing puppies. Our formula offers the right balance of high quality protein to help your canine live a long and healthier lifestyle.

Formula M.A.S.S. Weight Gainer also supports gut health through direct fed microbials (DFM). It is important to incorporate (DFM) into your canines daily diet to inhibit problem causing bacteria responsible for disturbances in the GI tract. Growth rate, feed conversion, and many diseases are closely connected with the overall function of the gastrointestinal system.

When it comes to a healthy canine supplement program we all want one thing results. Whether your goal is to increase your dog’s muscle mass or amplify performance levels, you want distinct results. In the quest for better results, many dog owners spend a lot of time and money only to fall short of their expectations. Here, we will provide you with some general and specific tips so you will not be one of these unsuccessful dog owners.
First we want to address an issue that comes up when owners are unable to get the results they are looking for. These owners tell us that the supplements did not work.
The problem does not usually lie with the supplement. In many cases, the dog owner does not work the supplement to its full potential. We can not emphasize enough, the importance of this. “Working the supplement” means that you use the supplement the way it is designed to be used in order to see its full effects. Another common reason that owners do not see the results they want is because they are using the wrong product. Many owners use a product thinking it will give them their desired result when the product is designed to give a completely different result. To get the results you want, you have to use a supplement designed to give you those results.
With these general guidelines in mind, take a look at some of our detailed tips where these basic ideas are put to use.
Our Formula M.A.S.S. Weight Gainer is designed to increase your dog’s healthy calorie intake. When it comes to adding muscle mass to your dog, this is a key factor. In addition to increased calorie intake, as the owner, you also play a key role in your results. First, you have to be consistent with your dog’s daily calorie intake. This means that you can not feed your dog 3 cups of kibble one day, then 2 cups the next day, then 4 cups the following day and get the results you want. You are not letting the supplement work the way it is designed to work. Stay consistent with your dog’s daily calorie intake in addition to using Formula Mass Weight Gainer and your results will be maximized.
A good exercise program is a key factor to making Formula M.A.S.S. Weight Gainer work. Let’s say you normally intake 1500 calories a day, but then increase your calories up to 4000 a day in hopes of building muscle. If you don’t work out in addition to increasing your calorie intake, the chances of you building muscle mass is highly unlikely. The same is true for your dog. If you want to add true healthy muscle mass to your canine, you have to exercise them.
We’ve seen time and time again, someone using a daily vitamin alone in search of adding muscle mass to their canine. While a vitamin/mineral supplement does have its benefits it will not increase your dog’s muscle mass without some help. If you are aiming to increase muscle mass Formula M.A.S.S. Muscle Builder is the product to use. Incorporate Formula M.A.S.S. Weight Gainer and see even better gains. The combination of increasing your dog’s healthy calorie intake along with a healthy muscle building supplement and exercise program are keys factors to amazing results!
While additional muscle mass is not a direct result of a vitamin or mineral, our research has shown that it is important to incorporate a daily vitamin/mineral supplement to provide your dog with the daily vitamins/minerals that dog food alone does not provide. By providing those vitamins/minerals you allow your dog’s body to function better which is important when it comes to making additional supplements work. The Best In Show Vitamin & Mineral Supplement and B.I.S. Future Star offer the vitamins and minerals needed to build a strong foundation in your canines overall health and development.
When incorporating a muscle building and performance supplement to your dog’s daily diet it is very important to work them out. The Formula M.A.S.S. Muscle Builder is designed to increase your canine’s muscle mass and performance levels in many ways. One of these ways is by repairing muscle tissue faster and more efficiently than a normal daily diet. To maximize these results you must first break down the muscle tissues to be repaired, through working out your canine. While you may see results just by normal daily exercise such as running in the backyard you will see even better results by increasing your dogs daily exercise program.
