  • Key Takeaways
    • Waterdog fish are actually not fish but amphibians closely related to salamanders.
    • Differentiating between a water dog salamander and a water dog fish can be confusing, but key differences lie in their physical characteristics and natural habitats.
    • The diet of water dogs varies depending on the species and includes small insects, worms, and sometimes fish.
    • Axolotls are often confused with water dogs but have distinguishing features.
    • Water dogs can make unique and fascinating pets, but they require specialized care.

What is a Waterdog?

Defining the Waterdog

The term “water dog fish” can be a bit misleading, as these creatures are not fish at all. They are actually a type of amphibian belonging to the salamander family. More formally, they are known as Necturus, and they are closely related to other water dogs amphibians like the mudpuppy.

LifespanUp to 18 years
HabitatFreshwater bodies

Physical Characteristics

A water dog salamander typically has a long, flattened body covered in a slimy, glandular skin. Unlike their terrestrial counterparts, they have paddle-like tails designed for swimming and lack the pronounced costal grooves found in many other salamanders.

Water Dog vs Salamander

Shared Traits

Both water dogs and salamanders belong to the same amphibian class and share many traits. They are cold-blooded, meaning their body temperature adjusts to their environment. Both types of animals are also predominantly carnivorous, feasting on a variety of small insects, worms, and sometimes fish.

What Do Water Dogs Eat?

One common question that people ask is, “What do water dogs eat?” The diet of a water dog largely consists of small insects, worms, and sometimes even small fish. Their feeding habits can be somewhat opportunistic, and they are known to consume whatever they can catch. In captivity, they can be fed a diet that mimics their natural prey, which often includes:

  • Insect larvae
  • Small crustaceans
  • Earthworms
  • Minnows

Water Dog vs Axolotl

Overview

The axolotl is another aquatic salamander that is often confused with water dogs. Originating from Mexico, axolotls have gained immense popularity as pets. It’s important to differentiate between axolotl water dog fish and water dogs to understand their unique requirements and behaviors.

Key Differences

FeatureWater DogAxolotl
OriginNorth AmericaMexico
Endangered StatusNot EndangeredCritically Endangered
External GillsPresent, but smallerProminent, feather-like
NeotenyPartialComplete
RegenerationLimitedExtensive (includes heart, brain)

One major distinction is that axolotls exhibit a condition known as neoteny, where they reach sexual maturity without undergoing complete metamorphosis. While some species of water dogs also exhibit neotenic traits, axolotls are known for their remarkable ability to regenerate lost body parts, including their heart and brain, which sets them apart from water dogs.

The Water Dog as a Pet

Care Requirements

Water dogs can make interesting pets for those willing to provide the specialized care they require. Some of the essential aspects to consider for keeping a water dog amphibian happy and healthy include:

  • Aquarium Size: At least a 20-gallon tank for a single adult.
  • Water Quality: Filtered, dechlorinated water.
  • Temperature: Between 60-70°F (15-21°C).
  • Diet: Carnivorous diet, similar to their natural prey.

Benefits of Having a Water Dog Pet

  • Low Maintenance: Compared to other aquatic pets, water dogs are relatively easy to care for.
  • Educational: Their unique life cycle offers a great educational experience.
  • Fascinating to Observe: With their peculiar behaviors and physical features, they are captivating to watch.

Having covered what waterdogs are, how they differ from salamanders and axolotls, what they eat, and how to care for them as pets, you should now have a thorough understanding of these fascinating creatures.

The Waterdog and Its Relatives

Water Puppy Salamander

Often referred to as “water puppies,” certain types of young salamanders bear a striking resemblance to water dogs. These water puppy salamanders are generally at an early stage in their life cycle and haven’t yet undergone the full metamorphosis to reach their adult form.

Salamander in Water vs Terrestrial Salamanders

When it comes to salamanders in water, not all species are fully aquatic like the water dog. Some salamanders divide their time between aquatic and terrestrial habitats. Knowing the type of salamander you’re dealing with can significantly influence the care it will need.

  • Fully Aquatic: Like the water dog, these salamanders spend their entire lives in water.
  • Semi-aquatic: These salamanders live both in water and on land at different stages of their life.
  • Terrestrial: These salamanders mostly live on land and only enter the water to breed.

Axolotl vs Salamanders: The Transformation Mystery

An intriguing question that often pops up is: can axolotls turn into salamanders? The answer is complicated. Axolotls usually remain in their larval form throughout their lives—a phenomenon known as neoteny. However, in rare circumstances involving hormonal changes or drastic environmental shifts, axolotls can metamorphose into a salamander-like creature. However, this transformation is generally risky and can lead to a shortened lifespan.

Water Dog Reptile? The Common Misconception

One of the most common misconceptions is referring to water dogs as water dog reptiles. However, it is crucial to understand that water dogs are not reptiles; they are amphibians. Reptiles have scaly skin and lay eggs with hard shells, while water dogs have slimy skin and lay gelatinous egg masses. The table below outlines some of these fundamental differences:

Water Dogs and Lizards: A Comparison

Another creature that water dogs are sometimes confused with is lizards. Though both have four legs and long tails, water dogs and water dog lizards couldn’t be more different. Unlike lizards, water dogs are fully aquatic and have specialized tails for swimming, whereas most lizards are terrestrial and have tails that serve different functions such as balance and defense.

The Ultimate Question: Are Water Dogs Fish or Amphibians?

There’s often confusion surrounding whether water dogs are fish or amphibians. To clarify, water dogs are not fish; they are amphibians. The term “waterdog fish” can mislead people into thinking they are dealing with a type of fish, but this is not the case.

Frequently Asked Questions

What is the Lifespan of a Water Dog?

The lifespan of a water dog can vary between species but is generally up to 18 years in the wild. In captivity, with proper care, they may live slightly longer.

How Do I Differentiate Between a Water Dog and an Axolotl?

Look for differences in external gills, origin, and ability for regeneration. Axolotls have prominent, feather-like external gills and come from Mexico, while water dogs have less pronounced gills and are native to North America.

Can Water Dogs Live with Other Fish?

While it’s technically possible, it’s not recommended. Water dogs are carnivorous and may prey on smaller fish. Additionally, the water conditions suitable for fish may not be ideal for water dogs.

What Do Water Dogs Eat in Captivity?

In captivity, water dogs can be fed a diet mimicking their natural prey. This includes small crustaceans, insect larvae, earthworms, and sometimes small fish like minnows.

Can Water Dogs Walk on Land?

Water dogs are primarily aquatic and have poorly developed legs, making them inefficient at moving on land.

Are Water Dogs Poisonous?

While not poisonous, some species of water dogs can secrete a slimy substance that may be irritating to human skin. Always wash your hands after handling them.

Is a Water Dog the Same as a Water Salamander Pet?

While similar, they are not the same. A water dog is a specific type of aquatic salamander, whereas the term “water salamander pet” could refer to various species, including axolotls and newts.

Understanding the water dog in comparison to its relatives, other aquatic pets, and even reptiles and fish, broadens our appreciation of this fascinating amphibian. This comprehensive guide should equip you with the knowledge you need, whether you’re an aspiring pet owner or simply curious about the wonders of the animal kingdom.
