What are Probiotics for Dogs?

Probiotics are microorganisms or bacteria that live in the digestive tract. They are essential in boosting the immune system of a dog, and also, they can be used when a dog is experiencing stomach or digestion problems.

Given that probiotics are bacteria living in the digestive tract, how then does one feed a dog? One feeds the dog by feeding the probiotics with prebiotic. Some of the prebiotic’s include bananas, apples, mushrooms and garlic among more.

How to Choose the Best Dog Probiotic for You

When choosing the best dog probiotic for you, you need to consider your dog’s personality and habits, ingredients, as well as any other conditions they may have. Here are a few things for you to think about when making your choice.

Capsules, Powders, or Chewables

As many pet owners know, giving your dog any type of medication or supplement can be tricky. Many dogs are picky eaters and won’t touch something they don’t like the smell of or the taste of. Other dogs will eat whatever you put in front of them. When choosing the best dog probiotic, you’ll need to consider your dog and the best way to get them the medication they need. My pup loves a good treat, especially if it’s beef, chicken, or bacon-flavored. He has no problem chomping down his heartworm medication, so it’s important to me that I choose a dog probiotic that he’ll eat.

Other dogs are so picky that they’ll simply refuse to put anything in their mouths if they don’t like the smell of it. In these cases, odorless or tasteless powder or opened capsule would suffice, so you can mix it in with something they already love to eat. The first step in getting your dog to better digestive health is making sure they’ll actually take what you’re giving them.

Ingredients

As pet owners, we’re responsible for everything our dogs put into their bodies. That responsibility is huge – it’s just like with your kids. You don’t want to give your dog something that is full of byproducts, additives, or chemicals. When choosing the best dog probiotic for your pet, be sure to check out the list of ingredients. As with dog food, the order in which the ingredients are listed indicates how much of that is in each serving. For example, an ingredients list with animal byproduct as the first ingredient is going to contain a whole lot of not-good-stuff for your dog, and less of what they actually need. If you’re the kind of pet owner who swears by grain-free dog food, you may also want to look for grain-free probiotics.

Another important part of checking the ingredients is making sure that the best dog probiotic for you doesn’t contain something that your dog is allergic to, or doesn’t particularly enjoy. If your dog is allergic to soy or chicken, you’ll want to stay away from any product that has those things in it. Similarly, if your dog’s stomach doesn’t do well with a certain food, you’ll probably want to stay away from anything with that in it. The goal is to improve digestive health by controlling gas and diarrhea, not adding to it.

Other Conditions & Health Issues

There are a lot of probiotics on the market today for you to choose from, and many offer additional benefits than helping regulate digestive health. When you are thinking about the best dog probiotic for you, consider what other things might be beneficial for your pup.

For example, if your dog is just getting over an illness or infection, they may benefit from the addition of antioxidants to help rebuild their immunity. If you have an older dog that suffers from arthritis and joint issues, perhaps a probiotic that helps with inflammation and contains glucosamine would be helpful. If you can address more than one issue with the same supplement, not only will it help your dog in multiple ways, but it’ll also be more efficient by using one supplement instead of multiple.

Benefits of Using a Dog Probiotic

Improving your dog’s digestive health can help them feel better and enjoy life. Just like humans, dogs do suffer from the occasional bouts of digestive upset like diarrhea, loose stools, and gas. It’s not comfortable when we’re going through it, and it’s certainly isn’t comfortable for our furry family members either. As responsible pet owners, it’s our job to look out for our dog. Adding a probiotic to your dog’s diet will help them feel their best, and you won’t have to deal with the smelly side-effects.

As an added improvement, improving digestive health in dogs will also lead to improved skin and coat issues. Many dogs deal with hot spots, excessive itching and licking, and yeast infections on their skin. These can be addressed by balancing the bacteria in your dog’s digestive system. The best dog probiotic will help your dog feel his best both inside and out. If dry skin is a big issue for your dog and it doesn’t go away, try giving them a dog itching and dry skin remedy.

Giving probiotics to dogs is beneficial. Probiotics help your dog specifically by:

  • Inhibiting the growth of harmful bacteria in your dog
  • Aiding in your dogs overall digestion
  • Strengthening your dogs immune system
  • Helping treat diarrhea, irritable bowel, and intestinal inflammation
  • May prevent urinary tract infections

Probiotics work by helping your dogs digestive system create what are called SCFA’s (short-chain fatty acids). SCFA’s help the digestive system by reducing or stopping the growth of harmful bacteria like E. coli and Salmonella.

Dog probiotics contain billions of beneficial bacteria. Many of these bacteria, such as Enterococcus faecium, Bacillus coagulans, Bifidobacterium animalis and Lactobacillus acidophilus have been shown to beneficial to aid with diarrhea and improve the dogs overall digestive system. to resolve in dogs. The bacteria Lactobacillus plantarum is also beneficial for dogs as well.

Precautions When Using Dog Probiotics

Our dog probiotic research looked at the list of specific probiotics (or the names of the individual strains of bacteria) in each product for sale. According to vets, (and this is true for their human friends as well), each strain of bacteria does something helpful and different for the body. In many cases, too many different kinds of bacteria can not be helpful as they tend to cancel each other out. Probiotics lose their effectiveness (die) over time. Use the probiotic product well before its expiration date.

Just like when you’re giving your dog a new food, it’s best to slowly start integrating it into their diet to prevent adverse reactions. Oftentimes with dog probiotics, the symptoms you’re trying to help get worse before they get better. This is because the body is adjusting to the sudden amount of good bacteria that it is getting. To help lessen this, it’s advised to start slowly giving a ¼ dose over the course of a week, and if tolerated, continue to ½ dose for another week, and so on. If your pet has any adverse reactions, stop use immediately and call your veterinarian.

As with any supplement or medication, it’s best to talk to your veterinarian about any type of dog probiotics before giving it to them. Your veterinarian knows your dog inside and out, and will be able to tell you what to look for and, more importantly, what to avoid in choosing the best dog probiotic for you. Each dog is different and has a different set of health requirements, and you won’t find a one-size-fits-all approach when it comes to probiotics.

Conclusion
