Sodium in dog food

Salt is a notable ingredient in all processed dog food because it is a necessary mineral. It also makes the food tastier so your dog will surely not refuse it.
A good quality dog food has around 0,3% salt, which is considered to be the safe quantity. That means less than 100mg of salt in 100g of food. That’s the percentage that you should keep your eyes peeled for. You don’t want too much but none at all causes just as much of a trouble.

Special low sodium dog food

Dogs need sodium as much as we do, that ’s clear. But some little pups need less than others.
Your furry companion has a brave strong hard that unfortunately beats at a very irregular rate. Salt has a big effect on how your dog’s heart functions, as it increases the arterial tension, making it beat like crazy, if present in overboard quantities. Low sodium dog food keeps the tension at bay, preventing fibrillations or abnormal heart rate. Besides prevention, veterinaries also recommend it to those dogs that are already suffering from such problems, as a treatment method along with medication. If you happen to have a pug or a cute bulldog then be wary as they have an increased chance of developing cardiac issues. They might already need the best low sodium dog food.

Speaking about issues, your dog’s kidneys are not big fans. Actually, they prefer potassium as it prevents congestions and the formation of stones. Going overboard with the salt can cause the kidneys of an older dog to stop working properly going into renal atrophy. Low sodium dog food keeps them hydrated and happy, preventing renal blockages. Small dogs such as Jack Russells, Yorkshire terriers and other from this category are very prone to kidney problems so make sure to keep an eye on their salt intake.

Regardless of breeds, young dogs can take salt well. If you have a pup that’s still in a permanent growth spur don’t get overly worried about the sodium levels he ingests, as long as its food fits the 0,3% rule. Food that has more salt can cause your dog’s stomach to get upset, and believe it or not ulcer can develop, as salt makes the gastric juices way more acidic than normal. This is the reason why we also included a product especially for sensitive digestive systems, that is sure to take care of that nasty acid.

But as dogs get older and their internal organs start to become lazier, going for the best low sodium dog food will give them the chance to fight possible diseases that are lurking in the shadows, praying for some extra salt.
