The Medium is 8.9″ around over 8.7″ usable, a girth-to-length ratio of 1.02. Owners short on depth filter for 1.3 or higher; this one sits under it.

Knot girth 5.7–12.2″, the widest point on every size we hold numbers for. The narrowest published point measures 3.5–7.3″.

Soft to firm on our five-step scale, across 2 Sinnovator labels.

Why
  1. “Medium”
    10A maker-published1
    Firm maker-published12
    10A is what Pleasure Forge, Strange Bedfellas, Fantasy Grove and Creature Feature all call FIRM. Sinnovator's 'Medium' is the industry's 'Firm'. Placed at Firm and flagged. Feels like: "A little give, nothing more. Harder to compress than our softer pours…" 1 same word, different silicone →
  2. “Super Soft”
    00-40 maker-published1
    Soft maker-published1
    "Around 40 on the Shore 00 scale." Top of our Soft band — a full two ladder steps firmer than what 'Super Soft' means at Pleasure Forge, Wandering Bard, Fantasy Grove or Strange Bedfellas (all 00-20). Feels like: "Plenty of squish. A favourite in the fantasy world…" 1 inverted naming →

No owner has filed a squish report on a Sinnovator label yet. At 3 we start printing what they found next to what the maker claims — one pour isn't a finding. File one →

Prices are the maker's own, read daily in GBP; 96 pours feed the line. The shape of the line is the maker's; only the labels are converted, at today's rate — so a past point shows what it would cost today, not what it cost then.

No restock interval yet. We've watched no restocks on this sculpt, and it takes 2 before a gap between two of them means anything.

Counted from our own daily log of the maker's listings — one row per listing per check, so a flat line means we looked and nothing moved. Days before we started tracking aren't counted, and days nobody checked aren't guessed at.

Asked plainly, 11 questions
How big is the X-Small Knotted Dog Dildo?

The X-Small Knotted Dog Dildo has 5.5″ of usable length and 5.7″ around at its widest, as Sinnovator publish it. It measures 7.1″ tip to base, but the base doesn't go in — usable length is the number that matters.

How big is the Small Knotted Dog Dildo?

The Small Knotted Dog Dildo has 7.1″ of usable length and 7.3″ around at its widest, as Sinnovator publish it. It measures 9.1″ tip to base, but the base doesn't go in — usable length is the number that matters.

How big is the Medium Knotted Dog Dildo?

The Medium Knotted Dog Dildo has 8.7″ of usable length and 8.9″ around at its widest, as Sinnovator publish it. It measures 11.0″ tip to base, but the base doesn't go in — usable length is the number that matters.

How big is the Large Knotted Dog Dildo?

The Large Knotted Dog Dildo has 10.2″ of usable length and 10.6″ around at its widest, as Sinnovator publish it. It measures 13.0″ tip to base, but the base doesn't go in — usable length is the number that matters.

How big is the X-Large Knotted Dog Dildo?

The X-Large Knotted Dog Dildo has 12.0″ of usable length and 12.2″ around at its widest, as Sinnovator publish it. It measures 15.0″ tip to base, but the base doesn't go in — usable length is the number that matters.

Soft or medium — which firmness of the Knotted Dog Dildo should I get?

Sinnovator offer it in “Medium” and “Super Soft”. On our common scale that runs Medium → firm and Super Soft → soft, each with the source behind it on our firmness table. Size moves the answer as much as the label does — Sinnovator say so themselves: Same girth-beats-label rule as everyone else: "a smaller toy will feel softer than a larger toy, despite being made from the same firmness of silicone", and "toys with varying diameters may feel as though they have differing densities throughout". Softer silicone also mutes texture, so if you're buying this for what the surface does, firmer keeps more of it.

What lube can I use with the Knotted Dog Dildo?

Sinnovator say silicone lube is fine. They name water-based, silicone-based and oil-based lube as safe. In their words: "Our premium platinum silicone is compatible with water, silicone, and oil-based lubricants. There is various information out there suggesting that silicone lubricants cannot be used with silicone sex toys; however, this is not the case with our platinum cured silicone. Indeed, we have carried out various tests and have not seen or received any reports of any adverse effects." It recommends water-based for plugs (it absorbs and locks the plug in place), grease/oil (e.g. Crisco) for wide toys needing stretch, and silicone lube for depth training and longer toys — with the caveat that silicone lube is harder to wash off and can trap bacteria and viruses. Makers genuinely disagree on this one, so a rule you've read on another maker's page may not hold here.

How do I clean the Knotted Dog Dildo?

Straight from Sinnovator: Soap and warm water after every use — soap strength depends on the lube used. Boiling (3–4 minutes, raised off the pan bottom), autoclave, dishwasher, or a 10% bleach soak for 10 minutes are all sanctioned. Always clean with soap and warm water before first use, and after every use. Soap strength follows the lube: water-based washes off easily, silicone lube needs a stronger soap, oil-based needs grease-cutting power. Boiling: stand upright on a grate in a tall pot, 3–4 minutes. Silicone insulates, so keep it off the pan bottom. Autoclave-safe too.

Will the Knotted Dog Dildo fit a harness?

Sinnovator offer Vac-U-Lock Compatible Base on some models: A uniquely shaped hole moulded into the base that fits Vac-U-Lock accessories — strap-ons and fucking machines. Dual-density dildos come with the Vac-U-Lock hole as standard. Sinnovator offer Vac-U-Lock Compatible Base With Suction Cup on some models: The Vac-U-Lock hole plus a removable Vac-U-Lock-compatible suction cup — take the cup out and the Vac-U-Lock socket is still there. Check the O-ring you already own before you buy.

How long will I wait for a Knotted Dog Dildo?

Toys are made to order with firmness, base, colour and pour style chosen at purchase. A 'Ready To Play' / 'Ready Made' range holds single stock units of a parent model at a fixed size and firmness. Their own stated windows — custom (made to order): "Custom Sinnovator creations, crafted to order, take 7-14 days". Those windows are the maker's own published figures.

Are the Knotted Dog Dildo's measurements verified?

Not yet. Every number here is a figure published by Sinnovator. When three or more owners measure the same point and agree within 2mm, we mark it verified and show the count — nothing on this sculpt has reached that bar.
