How Wide Is Your Dog's Nose?

[corvus]

I'm trying to figure out how far my LED and phototransistor need to be apart from one another to make a photointerruptor to suit a large range of dog noses. If you have a dog with a broad nose, I would love it you could measure how broad it is. I only know pointy-nosed dogs. I think my perception of how wide dog noses get is severely skewed. Just a rough estimate of the distance from one side of the snout to the other will do the job. A muzzle diameter rather than circumference, if that makes sense.

Thank you!

Do you want me to measures Charlie's?

Or his nose isn't broad enough?

[raineth]

Corvus, would Digby be at all helpfu (he has a big big boofy head)?

he is a mutt, so maybe he wouldn't be?

if he is, can you tell me if you want the diameter at the widest point (i.e. where the snout joins the face) or more toward the nose?

[WreckitWhippet]

perhaps you need to define for some what a brachy is

[raffikki]

I'm not really sure if you'd consider Rhino's nose wide, but the at the point of his nose it's about 9cm and back towards his eyes is roughly 11cm

[corvus]

Doesn't matter if he's a mutt. I'm looking for the diameter close to the nose. The idea is they touch a panel with their nose and break a light beam in the process. The closer together we can put the light and the light detector, the stronger the signal, but at the same time I don't want to make it cramped for dogs with big noses.

Charlie's nose is relatively little, but quite close to his face. Could you give me his head width, though?

[WreckitWhippet]

perhaps you'd best draw a little pic of exaclty where you want people to measure to and from

I have a shar pei what do you want

Yep no worries.

I'll measure him and send you the results later today

I can't draw piccies on my laptop. Track pads are evil.

If it makes it easier, you could just give me the circumference of the muzzle about 3cm back from the nose tip. I can work it out from that.

oh Digby is not at all bracchy, sorry I think I missed that bit.

I measured him anyway, incase its useful.

i did circumference: 36 c.m.

and diameter: 10 c.m.

with the diameter I got it from looking above.

I really hope it is useful because I got a big tongue kiss on the mouth from him and I know only half an hour ago he was licking his bottom

I measured Delta (Dane) and she was 8.5 cm (diameter).

I don't have brachy dogs but my Borders have a muzzle that's 1/3 the length of the skull. Is that suitable or do you want specifically Brachy dogs?

[D4DOGZ]

Shadow - Labrador

approx 3cm back is 7.5cm wide and 29cm around.

PS she is not a big lab weighs approx 32kg

Hope this helps

The other two are JRT x's - pointy noses sid you need those?

[OSoSwift]

Don't think pointy Whippet nose diameters will help!

Sounds interesting

[MolassesLass]

Not as bracchy as some in his breed but his muzzle would be about 7cm across and nose 4cm.

Bondi (Boxer) muzzle is 8cm in diameter, her nose is 3.5cm wide.

Thanks everyone, that's a big help.
