How Much Water Should a Jack Russell Terrier drink?

Hydrating your hound is very important since water makes up approximately 56 percent of an adult Jack Russell Terrier`s body weight (73 percent of lean body mass). Water is an essential nutrient for your Jack Russell Terrier`s existence.

Your Jack Russell Terrier needs to drink the right amount of water that suits its age, weight, and activity level.

Drinking too much water is not good for your Jack Russell Terrier, and neither is drinking too little water.

According to the recommendations by the vets at PetMD, a dog should drink, in milliliters, 50 times its weight in kilograms. That is, a 10 kg dog needs 500 milliliters of water (2.1 cups).

An adult Jack Russell Terrier weighs 6.8 Kg (15.0 pounds), and therefore requires 340.9 milliliters (11.5 ounces or 1.4 cups) of water every day, given that your dog is not a very active dog.

Essentially, the amount of water your Jack Russell Terrier needs a day depends very much on how much your Jack Russell Terrier weighs.

Also, the amount of water your Jack Russell Terrier drinks depends on your Jack Russell Terrier activity level. Very active dogs need more water than inactive dogs.

Use our Jack Russell Terrier water calculator to estimate how much water your Jack Russell Terrier should drink every day based on its weight and activity level.

The Jack Russell Terrier is generally a high-activity level dog breed. So, your Jack Russell Terrier will drink more water than the regular average dog breed.

Our Jack Russell Terrier water calculator above is based on the dog water drinking recommendation provided by the vets at PedMD.com.

However, PetMD`s recommendation applies only to dogs with low activity levels.

However, our calculator goes further to provide recommendations on how much water Jack Russell Terriers of different activity levels (low, medium, and high) need.

In our calculator, a medium-activity level Jack Russell Terrier needs one and a half as much water as a low-activity level Jack Russell Terrier each day. Similarly, a high-activity level Jack Russell Terrier needs twice as much water as a low-activity level Jack Russell Terrier needs.

One way to improve your Jack Russell Terrier`s water drinking experience is to buy your dog a water fountain.

A water fountain will also encourage your Jack Russell Terrier to drink enough water.

This is because the continuously flowing stream of water with a fresh taste from a water fountain will entice your Jack Russell Terrier to drink enough water.

Furthermore, pet water fountains continuously filter the water that it delivers to your dog. A water fountain ensures that your Jack Russell Terrier has access to clean fresh filtered water all the time.

Giving your Jack Russell Terrier water from a fountain is more hygienic than giving your Jack Russell Terrier water from a water bowl.

This is because water in the water bowl usually lays around all day, getting polluted as it lays around.

Here are the best water fountains that we recommend for your Jack Russell Terriers. These water fountains are durable, made with food-grade materials, and operate very quietly with little noise:

Also, your Jack Russell Terrier may drink less water if it does not have access to clean fresh water always.

Some dogs are picky drinkers, and they won`t drink water that is not fresh or water with dirt and debris in it.

If your Jack Russell Terrier is a picky drinker as such, then you should consider getting your Jack Russell Terrier a water fountain like one of these.

How to Tell if Your Jack Russell Terrier is Drinking Too Much, Too Little, or Enough Water

A simple way to check if your Jack Russell Terrier is drinking too much, too little or enough water is to first measure a large volume of water (many cups).

Then, at the start of the day, pour this water into your Jack Russell Terrier`s bowl so that your Jack Russell Terrier can drink water without a limit.

Then, in the evening, measure the amount of water left in your Jack Russell Terrier`s water bowl.

Then, subtract the amount of water left in the bowl in the evening from the initial amount of water that you put in the bowl in the morning. This will give you how much water your Jack Russell Terrier has drunk.

Finally, use our Jack Russell Terrier dog water calculator to check to see how the amount of water your dog has drunk compares with how much water your dog should be drinking for its size and its activity level.

This will tell you if your dog is drinking too much, too little, or just enough water.

Then you can switch to giving your Jack Russell Terrier water with a water fountain.

How To Tell If Your Jack Russell Terrier is Dehydrated

If your Jack Russell Terrier is not drinking enough water she may become dehydrated. Dehydration in dogs can have mild to severe consequences. Always be on the watch to prevent the accidental dehydration of your Jack Russell Terrier. Here are ways to know if your dog is dehydrated:

  • Check her gums: Press on her gums and release it; if it quickly becomes pink back, she is not dehydrated. If it remains white, she may be dehydrated.
  • Loss of skin elasticity: You can check your dog`s hydration level by pinching her skin. If her skin goes flat right away, that is a sign that your dog is properly hydrated. However, if it takes several seconds for your dog`s skin to go flat after a pinch, then that could be a sign that your dog is dehydrated.
  • Weakness and low activity: A dehydrated dog will be weaker and less active than usual.
  • Dry mouth: If your dog`s mouth is dry or if your dog salivates less, then she may be dehydrated and need water.
  • Dry Nose
