Does Dog Shampoo Expire

Does Dog Shampoo Expire: Personally, I don’t bother about my hair shampoo expiring, I just go ahead and use whatever I have left and move on with my life because it doesn’t even last enough to expire anyways. But some days back I had to give my dog a bath, and then it struck me, “how about dogs? does dog shampoo expire?”

Being a dog parent and even a human parent is a responsibility that one needs to take seriously. Our furry pups depend on us to provide them with home, love, and care, and most importantly make sure they are clean and healthy. Even if the dog views bathing as pure torture, it still must be done from time to time.

If like me, you bathed your dog recently and you just weren’t satisfied with the bath, or they are not just clean as they should be, or they’re irritable and itchy, you might have asked yourself that question, did his shampoo expire? did it go bad? does dog shampoo expire?.

The answer is YES Dog shampoo has an expiration date just like human shampoo. when purchasing, It is important that you always check the label on the bottle to determine how long it is safe to use. Using expired shampoo products can result in skin irritations or even infections for your dog. Once you notice the one you have is past its expiration date please throw it away.

Does Dog Shampoo Expire? (How to tell)

Does Dog Shampoo Expire

Dogs’ shampoo can expire and using it can harm both humans and dogs. Harmful bacteria can grow on the shampoo bottle and cause skin problems such as inflammation, allergies, itching, and fungus. Expired shampoo can worsen skin conditions and lead to serious health issues. All dog shampoos have expiration dates, which affect their quality and effectiveness. Manufacturers usually put the expiration date on the label, but not always. Check the bottom, sides, or back of the bottle for the expiration date. Your dog shampoo may be expired. Here are a few ways to tell for sure.

  • Open the bottle and look inside. If the color of the bottle or the substance inside has changed, it may be expired. Pour some out and smell it to check its texture. Expired shampoo can become watery or slimy and will not smell as good.
  • After checking the shampoo, observe your pet. Expired shampoo will not clean your pet as well, so make sure they are still clean and smell good.

Your dog may look clean, but if they scratch more or have dry, red, or irritated skin, throw out their shampoo and replace it. Don’t give it to your neighbor. Contact a groomer or vet for advice.

How Long Can You Use Shampoo After The Expiration Date?

I like to use expired stuff, but it’s not a good idea. The expiration date is important. Even a few days after it can be bad. The shampoo may not work well or cause problems. The guideline is there for a reason. It’s not worth the risk to use expired shampoo on your dog. Expired shampoo can be harmful because of chemical changes and bacteria. Don’t use it if it’s expired, just throw it out.

How Long Does Shampoo Last Once Opened?

Once opened, most dog shampoos will last around 12-18 months, however, organic shampoos can last longer, from within 1-36 months.

Dog shampoos can last for up to three years on the shelf after production, but once opened, the chemical compositions of the product begin to experience change and alter because of the oxygen or air going into it and so it expires surprisingly fast.

Contrary to the validity period of organic shampoo (which is made up of natural and environmentally friendly ingredients), medical shampoos, including flea shampoos, have a shorter shelf life so they expire quicker at around six months or less as their chemical composition is more complex.

If you want your dog shampoo to last longer, make sure to buy one that has an extended expiry date, and store it at a temperature range that was mentioned on the container label, if not the product could go bad faster than the date stated on the bottle or label.

How To Choose A Shampoo 

There are a couple of do’s and don’t when it comes to purchasing dog shampoo but the essential idea is to consider your dog, its size, age, and fur type, and find something that works for your dog.


  • go for soap-free shampoos
  • go for natural ingredients


  • buy shampoo without checking its expiry date
  • buy shampoo without checking the ingredients
  • choose scented shampoos

  • use human shampoo for your pooch

Just make efforts to look for shampoos suitable for your dog’s particular breed because only then will they have the best effect on their skin and fur. Also, if your dog is still a puppy, choose an appropriate shampoo that is gentler. you could also prepare a home-made one yourself

How To Store My Dog Shampoo 

To prolong the lifespan of your dog shampoo, there are some dog shampoo storage tips you can adopt. The perfect conditions for storing will depend on the composition of the product or its ingredient list. usually, you can find and follow instructions written on the label of the bottle, but you can also follow these guidelines:

  • do not open the bottle till you need to use it
  • Store the shampoo at room temperature
  • Keep the dog shampoo in a dry place
  • Keep the shampoo bottle away from heat and direct sunlight.

But you should take into cognizance that these recommendations may vary, as there are many different types of dog shampoos, from dry to liquid, from homemade and organic to medically made ones.

Can I Use Human Shampoo On Dogs Instead  

If your dog’s shampoo expired, and you’re thinking of reaching for your own shampoo to groom your pet, please don’t!. It’s called human shampoo, it was made specifically for humans and not dogs.

It is important to remember that a dog’s skin is more sensitive than that of a human, also, our pooches’ pH level varies from that of humans, and their skin needs more moisturizing components in their cleaning products. While the average human pH level is 5.5 to 6.5, the dog’s pH level is between 6.2 -7.5.

Human shampoos are too aggressive and can harm and disrupt the dog’s mantel, stripping it off all its natural oils, and leaving the skin dry and itchy. There are lots of different brands of dog shampoo to try, always choose one that’s suitable for your pet’s fur age, and skin, and also check its expiry date. but if you don’t know which one to choose, don’t hesitate to speak to the pet store or your local vet.

What to do if there’s no expiration date on the dog shampoo bottle

Let’s say you encountered a shampoo you would like to purchase for your pooch, but it doesn’t have an expiry date, well I’ll tell you straight up not to get it, but there are some other ways to find more information about it.

Some manufacturers don’t place an expiration date directly on their products. You may want to check their website or give them a call before or after buying their products just in case the expiration date has rubbed off or you forgot to check them.

Then Some shampoos may not have an expiry date but will have like a batch code on the bottle which you can check to see when the bottle was made.

If you still happen to find nothing, then you can follow the tip on how to tell if your dog shampoo is expired, and dispose of it after 12-18 months of use, depending on what type it is, or three years when it is unopened.

What are the side effects of expired shampoo?

As earlier established, the bacteria that grows on the walls of the shampoo bottle after expiration can cause several harmful skin conditions such as skin inflammation, allergic reaction, itching, red, flaky skin, and fungus. if your dog has really sensitive skin or skin problems, using an expired shampoo can worsen its condition and lead to other serious health complications if not treated, and we do not want that now do we?
