Let’s face it, humans are animals, and those animal instincts come out from time to time.

Sex is animal instinct, just listen to the Nine Inch Nails anthem “Closer” (the lyrics aren’t exactly subtle).

While there are many different ways to answer this call, let’s talk about satisfying these primal urges with a particular type of sex toy: animal dildos.

Animal Dildos 101

Defining Animal Dildos

When the animal comes out in you indulge your instincts with an animal dildo. Canine or knotted dildos are fantasy toys with unique features that deliver amazing benefits. If you have ever had a wolfman fantasy or a fetish for knotted dildos that expand in just the right spot, an animal dildo might be the ideal solution. These toys can replicate the act of tying in which a bulbous gland in the penis swells while inside a partner.

This sensation doubles the pleasure of penetration as many animal dildos are either inflatable or feature a knot which simulates the characteristic bulb. This knot provides intense vaginal or anal sensations making canine dildos very popular with men and women alike. These unique items are great for solo use or role playing, especially if one if is acting out an animal fantasy. The design of these sex toys provide stimulation one cannot achieve from a regularly shaped phallus which sets them apart in the fantasy genre.

When choosing an animal dildo a person needs to take into consideration size, design, materials, and their user level when it comes to sex toys. Knotted/canine dildos come in a wide array of sizes and styles to accommodate an equally wide array of users. The most important thing to keep in mind is your comfort level as sex should be enjoyable. Some animal dildos can be rather large and I don’t recommend these to beginners who should gradually work their way up to larger toys.

Realism is another element to think about as some animal dildos are extremely close to the real thing while others are purely fantasy products. Keeping this in mind, here are several items sure to bring out the animal in you.

1. Kadahr


Available from the appropriately-named Fetish Zone, Kadahr is about as real as it gets. This toy is available in small or large (based on your user level) and is made of 100% medical grade silicone.

It looks like a smooth, basic phallic shape until you reach the bulb. The included inflation tube allows you to inflate the knot to any boundary of your comfort level for vaginal or anal use to replicate the act of tying.

The small has a length of 8.5” with 7.5” insertable and the length from tip to knot is 4”. The shaft circumference is 3.75” to 3.85” and when inflated the knot circumference can reach up to 8.5”. Before inflation the know is the size of a golf ball, making the small an ideal size for beginners.

The large has a length of 11” with 9.5” insertable and the length from tip to knot is 5”. The uninflated knot measures 6.75” and its maximum inflated circumference is 11”. Based on these dimensions one can see why novices might want to opt for the smaller size. For those looking for a truly realistic experience the Kadahr can be filled with warm water instead of air.


  • Made of premium, body-safe silicone.
  • Waterproof.
  • Two sizes available.
  • An extremely realistic toy.


  • A high price point.

2. The Royal Hound

For those looking for a simpler canine dildo consider the Royal Hound. While it does not replicate the natural process of tying, this toy does feature a beautifully-shaped knot. It is also made of 100% silicone but only comes in one size with a total length of 8.7” with 7.5” being insertable, a 5.7” shaft, and a knot circumference of 7.7”.

The minimal, well-placed veins on the shaft allow for increased pleasure as does the triangular head with a diameter of 1.2”. While suitable for vaginal or anal play, the well-shaped head does allow for fantastic clitoral and/or G-spot stimulation. With a medium firmness level, this canine is just the right mix of stiff yet flexible so you can reach all the right spots.


  • Made of high-grade silicone.
  • Great price point.
  • Excellent user reviews.


  • No suction cup.

3. Romi

Made of body-safe TPE for a truly skin-like feeling, the Romi is a waterproof, flexible canine dildo that not only has the characteristic know but is designed for additional G-spot and clitoral pleasure. As far as penetration goes this purple beauty is a total of 7.28” in length and features a strong suction cup base for hands-free enjoyment.

The shaft is covered with a veined texture for extra internal sensation (and that’s before you pop the knot in) but what I would like to focus on is the slightly concave tip with its tiny hole. This allows for light suction of the clitoris while it is “hugged” by the inward curve.

The shape of the head, combined with the excellent flexibility, delivers amazing G-spot stimulation while the veins and knot provide even more internal pleasure. And yes the Romi can also be used anally. This toy is fully waterproof and with its soft texture feels amazing in the bath or shower. If you are going to use it (or any toy on this list) in the water just be sure to have good quality water-based lube on hand.


  • The specially shaped tip for clitoral stimulation.
  • Excellent price.
  • Waterproof.


  • Jelly-like TPE needs a lot of cleaning.

4. Rex

Rex Dildo

Bad Dragon is among the Rolls-Royce of sex toys and Rex is one of its standout canine dildos. While they can be on the pricey side Bad Dragon products are handmade from 100% platinum grade silicone and boast design features that take pleasure to entirely new heights.

As several of their products, including Rex, are completely customizable they appeal to users ranging from novices to sex toy veterans. Rex has a fairly small, rounded head with an almost nipple-like protrusion complete with a tiny hole. Do I even have to tell you how amazing this feels for clitoral and labia stimulation?

If you prefer anal use Rex does not disappoint due to its superior design. The shaft is slightly textured with realistic veins before coming to the large, bulb-like knot. This toy’s length delivers amazing internal play and the knot keeps it perfectly in place.

Due to size and firmness options, Rex can be enjoyed by almost any user. For beginners, please take time to learn how to use this toy and fully enjoy the amazing “tickler” on the head! If you are new to sex toys go with the mini (6” overall, 5” insertable, 3.25” shaft, 4.75” knot) or the small (8” overall, 6.5” insertable, 4.36” shaft, 6.27” knot).

If you are an absolute novice choose the mini as even the small might be a little much, especially the knot. For experienced users, Rex can go up to an extra-large with a whopping 14.5” length, 12” insertable and a 7.5” shaft leading to a 11.25” knot.


  • Fully customizable.
  • Mini size perfect for beginners.
  • Unique design features.
  • A reasonable base price.


  • No suction cup.
  • Only available in two firmness options-soft & medium.

5. Razor

Razor Dildo

This long-time favorite from Bad Dragon is more wolf than dog as it will have you howling with pleasure. The Razor is a girthy, challenging beast that is as versatile as it is satisfying. Like all of the manufacturer’s products it is crafted from premium grade silicone and completely body safe.

A smaller base makes this toy very easy to maneuver vaginally or anally and the pointed tip (head) is perfectly shaped for intense external stimulation.

The concave underside begs to caress the clitoris while the sculpted tip offers a targeted massage. Needless to say that tip can also work wonders on the G-spot as one enjoys the penetration of the smooth, generous shaft.

The short shaft leads to this dildo’s crowning feature: an enormous knot. Note to even seasoned users, you will need a lot of lube for this. The Razor is not for the faint of heart as there will be stretching involved, but for those seeking substantial girth this is an ideal option.

Even though it is available in small, the circumference of the knot is an impressive 5.85”. If you are a beginner, be sure to order this size and work you way up to the know slowly. Keep in mind you will be getting amazing clitoral and G-spot stimulation before you even get to the know. If you’re a sex toy veteran, the large boasts a 6.25” shaft and 10.25” knot. When it comes to flexibility, the Razor is available in soft, medium, or firm.


  • Customizable size, firmness, and color.
  • Sculpted tip for enhanced pleasure.
  • Smaller base for greater ease of use.


  • A little expensive.
  • Not available in a mini for beginners.

The Best in Show

The winner of this show goes to Rex.

Animal, especially canine, dildos are known for realistic feel such as the knot and texture. Not only does Rex have these features but the toy features the small protrusion on the head for targeted stimulation. The characteristic knot is flawlessly shaped and designed to hold the length of the dildo in place for intense pleasure.

The textured shaft delivers even more stimulation when used for thrusting before “locking” the dildo with the beautifully sculpted bulb. The Rex is also appropriate for any user thanks to its size options (especially the mini) but only two firmness levels might be disappointing to some. Overall, you can’t go wrong with this gorgeous dildo as it will bring out the animal in you.
