Update on Frodo the Faller

Yesterday’s excitement proved a little too much for Frodo – or maybe it was nothing at all to do with it – but last night he had three fits. They were all mercifully short but disturbed him. He always paces for about ten minutes after he recovers consciousness and seems quite tired today.

We weren’t going to take him out but have decided that fresh air and sniffs will do him good – and the Labradors – and us, of course. Naturally, the sniffs we will enjoy will not be in quite the same league as the ones the dogs appreciate. 

Dogs have an extraordinary sense of smell. They can identify smells one thousand to ten thousand times more accurately than we poor humans. The smell analysis percentage of a dog’s brain is 40 times larger than that of a human’s.

The following table, from ‘Understanding a Dog's Sense of Smell’ by Stanley Coren, PhD and Sarah Hodgson, emphasises the paucity of the human sense of smell compared to that of different breeds of dogs. (The heading seems to suggest that there are different breeds of people, too – and there are some who would not refute that!)

Table: Scent-Detecting Cells in People and Dog Breeds

Species	Number of Scent Receptors
Humans	5 million
Dachshund	125 million
Fox Terrier	147 million
Beagle	225 million
German Shepherd	225 million
Bloodhound	300 million

 

Given these facts it is even more amazing to discover that the canine sense of taste is less well developed than the human’s. The main taste sensations are the same – sweetness, sourness and saltiness – but as dogs wolf down their food without first carefully smelling it as cats do it would seem that the smellier the food is the more eagerly dogs will consume it. This explains why dogs will eat anything they regard as having an attractive aroma – rotting carcases, mouldy food, anti-freeze will all be ingested with gusto.

 I hope Frodo won’t have any more falling down practices in this cluster - we will be watching him closely for the next two or three days. 

Camera Critters #72 noses and paws

I love dogs' noses. Jenna-the-Labrador was playing with Gentle Dominie yesterday. Dominie really enjoyed it. She can't initiate play now but she's still very much an alert and interested dog. She comes into the kitchen every evening nose a-twitch when I'm preparing supper just in case there are any titbits to be had.

A dog's sense of smell is thought to be 100,000 times better than a human's. Dogs can smell things as diverse as drugs, electricity, underground gas pipelines, insects in woodwork. They can smell week-old human fingerprints. Specially trained Jack Russells are used to detect brown tree snakes in the loading bays of aircraft in Guam. Dogs can even smell illness and can alert their owners to pending heart attacks or epileptic seizures. Their accuracy in detecting some cancers is greater than hospital scanners.

A gentle nudge from a dog's nose is one of the most trusting and loving acts a dog can perform.

I also love dogs' paws. These belong to Jenna - she has amazingly large feet for a relatively small dog. Labradors' feet are slightly webbed making them fast and efficient swimmers. In their original homeland of Newfoundland they were used by the fishermen to haul in their nets from the icy sea. Their thick wiry coats insulated them from the cold. A Labrador's coat can hold an enormous volume of water and onlookers are advised to stand well away when one or more Labradors emerge from deep water unless, of course, they like a cold, usually muddy shower!
