Your Dogs Intelligence - Could Dogs Be Smarter than Their Owners?
The intelligence of the dog is among the highest of all the animals, maybe higher than we give him credit for. Although his brain is proportionately only half as large as ours, he is certainly the most intelligent of domestic animals.
As with humans, individual intelligence varies greatly according to inherited genes. While no one breed can be said to be more intelligent that another, some breeds that have been selectively bred for work ability are often brighter and more receptive than those bred primarily for purely physical attributes.
Whether a dog is a mixed breed for purebred, studies have shown that neither is much more intelligent than the other. However, dogs that have been exposed to a more varied lifestyle, both indoors and out, and with both human and animal interaction, does show more intelligent behavior.
Simply put, giving your dog an opportunity to investigate and manipulate all sorts of objects, to explore all sorts of places, to share all sorts of experiences with you will stimulate his or her intelligence. Aside from getting a lot more out of life, your dog will be eager to learn more and he will learn with increasing ease and rapidity. Nothing is sadder and more wasteful than an intelligent dog that is confined in a kennel and deprived of mental stimulation.
Despite opinions to the contrary, dogs are endowed with an elementary reasoning power. Anyone who has ever owned a dog has often seen him size up a situation and then taken some logical action. Guide dogs for the blind, as well as working and hunting dogs of many breeds constantly have to use their judgment and make decisions.
Memory is an important component of intelligence. The dog's memory for scents is extraordinary. His visual memory is only fair, but his memory for sounds is very good, since he can remember and identify familiar voices even after an absence of many years. While he builds up a large store of identifiable sounds without the slightest effort, remembering different words requires more concentration.
The dog's capacity for learning is more a matter of memory than of true understanding. He will remember the sequence of cause and effect in his actions, but he is unable to draw broad conclusions from his experience. The greater the variety of experiences and contact with others they have, the quicker they learn, and the more they retain.
Dogs are bound by nature to remain intellectually inferior to man, but we owe them a chance to develop their native intelligence by training, teaching, and working with them as much and as often as we can.

Pet Insurance. Obesity is cutting many pets' lives short.
Petplan, one of the UK's most popular pet insurers, has revealed that 60% of pets can be considered obese.
Owners treat their beloved pets with what they feel will do them good – fatty snacks, titbits from the table – in addition to the large portions of food they already eat at mealtimes. As a result, pet insurance claims due to health problems directly related to being overweight are spiralling.
So what are the facts? Petplan insures 800,000 pets in the UK, and in the last five years they have seen obesity related health claims increase by 60%. The result - pet insurers could start slashing payouts as a penalty if your pet is overweight.
So what health problems can an overweight pet experience? Common problems include joint, ligament and tendon issues, problems with breathing, overexertion on the heart, and diabetes. Large, overweight cats can develop skin disorders because they are not able to clean themselves properly. The long-term effects on your pet's health and lifespan could be disastrous.
It's not all bad news though – putting your pet on a diet is a lot easier than doing the same to yourself. At least your pet has no choice in the matter, and doesn't have to deal with the temptation of the Indian takeaway after a hard day at the office, or that second, third, fourth (!) glass of wine. Your pet can only eat what it's given, so you can take control of the situation. The weight of your pet is your responsibility, so if it is overweight then it's your job to remedy the situation. It's not all about food either, if you have an overweight dog then take a bat and ball on the walk and really get that doggy working out! It will do you some good too.
Here's how to tell if your pet needs to lose some weight. Of course your pet will have a certain amount of padding, but there shouldn't be too much. First off, rub your pet gently over their ribs, you should be able to feel them without any trouble and the skin should move over the ribs quite easily. Then take a look at your pet from the side from a few metres away. If your pet has a hanging stomach and looks like it could be expecting some babies, then it's definitely time to introduce a diet. Your pet's stomach should slope in to form an obvious waist area at the bottom of the rib cage. Now stand over your pet and take a look from above. If your pet's middle is bulging out to the sides like an apple then it's carrying extra weight.
It's not just the four-legged friends either, birds can also be overweight. Examine your bird for rolls of fat or a larger than usual breast area.
Some breeds and species of pet have weight problems inherent in their genetic make up.
For the dogs: Labradors, spaniels, beagles, corgis and retrievers are all genetically predisposed to becoming overweight, especially as they get older.
For the cats: less-active breeds, Persians for example, put on weight as they don't do much exercise. Zany, fast moving breeds like Abyssinians and Siamese usually keep the weight off.
For the birds: Amazon parrots are particularly prone to piling on the ounces.
If you have just come to the conclusion that your pet is overweight, don't be tempted to put your pet on a crash diet. Cats can develop a fatal liver problem if their food rations are suddenly cut and they lose weight at a fast rate.
Pets put on weight gradually so the reverse should be applied and their food allowance should gradually be cut. Stop giving them snacks between meals and stick rigidly to set mealtimes. They'll soon get used to the new regime. You can also introduce more exercise to help them get fitter and also improve their quality of life. Ask your vet for advice on how best to put your pet on a diet, and commit yourself to carrying it through. You owe it to your pet.
