Despite their similarities, Water Dogs and Axolotls are very different creatures with unique characteristics and traits. Understanding the differences can help potential pet owners decide which salamander would best fit their lifestyle and needs.

Understanding the Differences 

Water dogs and axolotls are frequently mistaken for one another because they share a resemblance in appearance and have similar names. 

However, these species have significant differences that set them apart in several aspects.

Species and Physical Characteristics Differences

Water dogs and axolotls are salamanders but belong to different genera. Water dogs belong to the Necturus genus, while axolotls belong to the Ambystoma genus.

Appearance Variations

One of the most noticeable differences between water dogs and axolotls is their appearance. Water dogs are more significant than axolotls, ranging from 8-18 inches, while axolotls grow to around 9 inches. 

Additionally, water dogs have a more elongated body shape with a flattened tail, while axolotls have a rounder body shape with a longer tail.

Development and Lifespan Variances

Another significant difference between these two species is their development and lifespan. Axolotls are known for retaining their larval form throughout their lives, while water dogs metamorphose into adult mudpuppies or hellbenders. Axolotls have an average lifespan of 10-15 years, while water dogs can live up to 20 years.

Gills and Habitat Differences

Axolotls and water dogs also have differences in their gills and habitat. Axolotls retain external feathery gills throughout their lives, while water dogs lose internal gills as they mature into adult mudpuppies or hellbenders. 

Axolotls are aquatic and primarily found in Mexico’s Lake Xochimilco, while water dogs are semi-aquatic and can be found in North America’s freshwater bodies.

Comparison: Axolotls vs. Water Dog Fish

Axolotls and Water Dog Fish are both amphibians that belong to different species. While they share some similarities, there are also many differences between them. 

Habitat Differences

Axolotls are aquatic animals that live exclusively in freshwater, while Water Dog Fish can live in aquatic and terrestrial environments.

Axolotls are native to Mexico and can be found in the wild in the lakes and canals of Mexico City. Water Dog Fish, on the other hand, are found in various parts of the United States, including the Great Lakes region.

Physical Differences

Axolotls have a distinctive appearance, with external gills, a broad head, and a long tail. They come in various colors, including black, brown, and white. 

In contrast, Water Dog Fish have a more elongated body, with a flattened head and a long tail. They are usually brown or gray and have rough, bumpy skin.

One of the most significant physical differences between Axolotls and Water Dog Fish is their ability to regenerate limbs. Axolotls can regenerate their limbs, spinal cord, heart, and other organs, while Water Dog Fish cannot.

Transformation and Metamorphosis Variations

Axolotls are unique in that they do not undergo metamorphosis like other amphibians. Instead, they remain in their juvenile form throughout their lives.

This process is known as neoteny. In contrast, Water Dog Fish undergo metamorphosis, transforming from aquatic larvae into terrestrial adults.

Axolotls and Water Dog Fish also differ in their ability to breed. Axolotls can breed in their juvenile form, while Water Dog Fish must undergo metamorphosis before they can breed.

Unique Characteristics and Care

Water dogs and axolotls are unique creatures requiring specific care to thrive in captivity. Understanding their unique characteristics and care requirements is essential for any pet owner.

Axolotls possess a remarkable ability to regenerate lost body parts due to retaining their larval form throughout their lives. This allows them to regenerate limbs, spinal cords, and portions of their heart. However, Water dogs lack this regenerative capability.

Axolotls and water dogs act as bioindicators, are sensitive to environmental changes, and reflect the health of their ecosystems. They demonstrate high adaptability, thriving in both aquatic and terrestrial environments.

The care requirements for axolotls and water dogs differ. Axolotls need a fully aquatic environment with temperatures between 60-68°F, whereas water dogs can thrive in aquatic or terrestrial habitats with temperatures between 60-75°F. Axolotls have external gills, while water dogs have lungs and feathery gills.

Both axolotls and water dogs need a balanced diet consisting of live or frozen foods like brine shrimp, bloodworms, and earthworms. It’s crucial to ensure sufficient food for axolotls to prevent cannibalistic behavior in response to food scarcity.

In terms of appearance, water dogs are typically larger and darker in color than axolotls. Water dogs can range from 8-18″ in length and are usually a shade of olive, while axolotls grow to around 9″ in length and can come in various colors.

Physical Characteristics

Adult salamanders, including water dogs and axolotls, have several unique physical traits distinguishing them from other amphibians. When comparing water dogs and axolotls, there are several differences in their physical characteristics.

One of the most notable differences between Water Dogs and axolotls is their size. Water dogs are generally larger, ranging from 8 to 18 inches, whereas axolotls usually grow to around 9 inches. However, the size of an axolotl can vary based on their environment and diet.

Another difference is their tail. Axolotls have a long, feathery gill-like tail that they use to propel themselves through the water. In contrast, water dogs have a shorter, more muscular tail that they use for swimming.

Regarding appearance, water dogs and axolotls share some similar physical characteristics, but they are drastically different in appearance. Water dogs have a more robust body, while axolotls are more slender. Also, axolotls have more prominent heads and larger eyes than water dogs.

Regarding colors, axolotls come in various colors, including black, brown, gold, and white. On the other hand, water dogs are typically brown or gray with a mottled pattern.

Lastly, water dogs and axolotls have unique physical features that set them apart. Axolotls can regenerate their limbs, spinal cord, heart, and other organs. On the other hand, water dogs are often mistaken for dogs due to their name, but they cannot bark or vocalize like dogs.

Ownership and Care

When owning a water dog or an axolotl, specific considerations and care requirements must be considered. These aquatic pets require care, attention, and maintenance to thrive in their environments.

Care Requirements

Water dogs require a tank of at least 20 gallons, while axolotls require a tank of at least 10. Both pets need a filter to keep their water clean and toxins-free, and regular water changes are necessary to maintain water quality.

The water temperature should be between 60-75F for both pets, and a platform or shade should be provided for them to rest on.

Regarding diet, water dogs are carnivorous and can be fed pellets, earthworms, bloodworms, shrimp, crustaceans, snails, and insects. Axolotls are also carnivorous and can be fed pellets, earthworms, bloodworms, brine shrimp, and small fish. Feeding them appropriately and not overfeeding them is essential, as this can lead to health problems.

Habitat and Tank Setup

Water dogs inhabit freshwater lakes, rivers, and swamps in eastern Northern America and Canada, favoring clear waters with vegetation or hiding under stones and debris during the daytime.

On the other hand, axolotls are native to South America and thrive in tanks with sandy bottoms and ample hiding spots, like plants, rocks, and caves.

Both pets have external gills, which means they require a certain level of oxygen in their water. Their tanks should have a filter to keep the water oxygenated, and it is essential to avoid using any chemicals or additives that could harm their gills.

Lifespan and Reproduction

Water dogs have up to 25 years in captivity, while axolotls can live up to 15 years. Both pets can regenerate their limbs, spinal cord, heart, and other organs. Axolotls can also reproduce in captivity, but it is important to note that breeding them can be difficult and requires certain conditions to be met.

Coexistence and Compatibility

Keeping a water dog and axolotl together is possible but comes with challenges and risks. While both are aquatic and share some similarities, they are different species of salamanders and have different needs and behaviors.

Axolotls are native to Mexico, specifically the Xochimilco Lake in Mexico City. They are neotenic, which means they retain their larval characteristics into adulthood and remain aquatic.

Water dogs, on the other hand, are found in North America, from Canada to South America. They are also mudpuppies and amphibians that spend some time on land.

One of the main challenges of keeping them together is that axolotls have been known to eat smaller fish, including other salamanders. Water dogs are larger than axolotls and may be able to defend themselves, but it is still a risk.

Another issue is that axolotls have delicate gills that rough or sharp objects, including the teeth of a water dog, can damage.

Householding them together in a large tank with plenty of hiding places and separate feeding areas is possible. However, monitoring them closely and separating them if any aggression or harm is observed is crucial.
