What Do Dogs see?

wendy — Wed, 18 Mar 2009 16:16:38 +0000

It was once thought that dogs see only in black and white. However, this appears not to be true and they can distiguish between some colours.

So it would appear that:

WE see RED, THEY see pale yellow

WE see ORANGE, THEY see pale yellow

WE see BRIGHT YELLOW, THEY see pale yellow

WE see GREEN, THEY see pale yellow to white

WE see TURQUISE, THEY see white to pale blue

WE see DARK BLUE, THEY see mauve

WE see DARK PURPLE, THEY see grey

In the sport of agility, it’s important for the dogs to be able to see the obstacles clearly against the background in order for the dog to safely negotiate those obstacles. For that reason, the contact obstacles are painted in a contrasting colour to the contact area and the weavepoles and jump bars are striped in a contrasting colour. This is where “contrasting” becomes subjective. Bear in mind that dogs don’t see what we see, so what might seem like a contrasting colour (e.g. orange against green) is actually a same-shade to a dog!

Food for thought!

There are two very interesting articles in the January and February 2009 editions of Clean Run covering this subject and more. Well worth checking out.

The Art of Food Photography

wendy — Wed, 11 Mar 2009 17:41:33 +0000

I’m following a course from the PPSOP called “The Art of Food Photography”. Who’d have thought taking photos of food could be so hard! The first assinment is supposedly simple. Take a photo of something like an apple or an orange in natural light. Then take a photo of something with texture, like bread or a muffin. I found out that oranges have lots of texture and the stale loaf of bread I had in the cupboard didn’t look very appetizing. I fished out four rainbow cookies from a project I did a couple of weeks ago and shot those instead.

Three of the dogs are off to Alta Vista today for their CERF eye exam. It’s Marco’s first time with the drops. Should be fun trying to get them in!

Fun Match

wendy — Sun, 11 Jan 2009 04:37:04 +0000

Took 4 of the beasties out to RedGate for a fun match today. They all did pretty well! Ivan’s coming along nicely. Indy’s still a bit of an airhead.

It was cold. About -14C during the day but the sun helped make it feel warmer than it was.

A good weekend

wendy — Tue, 06 Jan 2009 21:06:45 +0000

First agility trial of the year. Morningstar in Kingston.
Tyra didn’t get off to a good start on Friday. Took down bars and avoided the tyre. Dropped her to 22″ specials the rest of the weekend and she came home with 11 Qs!

So have you all been Naughty or Nice?

Me, I haven’t opened my presents yet but I don’t see anything that looks like coal under the tree.

New Blog

wendy — Tue, 23 Dec 2008 04:51:34 +0000

I decided that instead of traditional html pages I would go with a blog type page instead.

Some of the old pages have been added to the pages section and I’ve generally had a good old clearout.

Let’s see how it works out
