Features to Consider for the Best Dog Lysine Supplement

Deciding on the best dog lysine supplement can be a difficult task. You must find the one that best suits its health needs while making sure it does not cause any adverse reactions in the short or long term. However, there are several features and options you can choose from in order to find the right one for your pet. In this section of the guide, we’ll go over the different delivery methods and ingredients of lysine supplements so you have a better understanding of Lysine products and choosing the right supplement for your pet.

Delivery Method

Chewables

These can often be used as treats for your dog, as they have a really good ability to cover up the smell of pure lysine, which most likely isn’t the most appetizing smell to them. The chewable flavor is typically chicken liver made from a mechanical extracting process similar to how jerky meat is produced. From the mechanical extraction, the lysine supplement is then embedded into the food, producing a chewable protein your dog can gobble down without any thought to what they are actually consuming.

Pills

While they aren’t the most ideal form to deliver supplements in, pills work well because of the milligram amount of the supplement they have. Pills are also the most veterinarian recommended because they are specifically created with the health of your animal in mind. On the other hand, they aren’t developed with the psychological effect of your dog, so lysine pills should only be delivered if they are prescribed by an expert veterinarian. There are also calming treats for dog anxiety available, which may help dogs who are taking lysine as a pill.

Powder

If your animal does not have a positive reaction towards chewable treats or pills, you can try the method of getting pure lysine powder and mixing it into its bowl. The key here is to use softer food, which allows the powder to be mixed in. For dogs, this might be tricky as they need to eat kibble, but you can sprinkle some of the powder onto the food without your canine knowing.

Ingredients

Pure Powder

Pure lysine powder does exactly what it needs to do for your animal, but you need to mix it into the food in order to get the proper results. Even hiding it in the food can be a good idea, as animals can sense when they are being given food not lining up with their normal dietary routine. Pure powder is also a good alternative to other chewable treats if your dog does not react well to the ingredients found in the lysine-embedded treats.

Meat Treat

This is a great option for dogs who are not a fan of taking a lysine pill. You can also "knock two birds with one stone" by incentivizing your dog to take this "treat" by behaving well. As a result, your dog will be well-behaved and healthy due to being treated with Lysine supplements when it behaves properly.

Vegetarian Treat

If you are animal-conscious and want your pet to be as well, it is important you get a lysine product with not only the right amount of supplement for your pet, but also embeds the supplement in a safe and natural way for your pet to consume. Being a vegetarian should not come at the expense of your animal’s necessities.

Benefits of Using Dog Lysine Supplements

If you have noticed your dog is not producing quality eye tearing or has less-than-ideal skin, you will want to look into adding a lysine supplement in addition to its other dog probiotics and dietary regimen. The amino acid lysine works by acting as the building block for proteins, which can go on to generate the enzymes needed for healthy skin and immune system function. This can be beneficial to older dogs who are taking senior dog vitamins.

Additionally, if you see your pet is having constant sinus troubles like wheezing, coughing, sneezing or a runny nose, lysine supplements can be beneficial as they allow the body to react better to attacks on the immune system from a variety of foreign pathogens. Lysine works by entering the body as an amino acid before starting a biochemical chain reaction, resulting in proteins being developed and leading to healthier and stronger bodily structures and an upgraded immune system function.

Precautions When Using Dog Lysine Supplements

Because lysine is such a potent amino acid in the body, you will want to avoid adding too much to your pet’s diet, as this can result in acute renal failure from kidney damage. This occurs because one of lysine’s biochemical functions is increasing the kidney’s ability to absorb calcium, which makes the skin and bones stronger when your dog takes the lysine supplements.

On the flip side, an excess of calcium take-up in the kidneys can cause gallstones and result in renal disruption and failure. Make sure to give the recommended dosage to your pet and always be sure to consult with your veterinarian before embarking on a strict dietary regimen. You wouldn’t want to start a strict diet with only the best of intentions and end up causing them harm only because you are using too much of what they need.

Conclusion

Hopefully, this guide has given you a better understanding of how lysine can prove beneficial and why adding it to your dog’s routine is so important to their health in regards to their skin, bones, and immune system.
