High Activity v Low Activity Breeds

People have a perception that the smaller their property the smaller the dog they should have. To a certain extent this is true, one would definitely not recommend that someone living in a small complex should ever get a Rhodesian Ridgeback or a Labrador, however amongst all breeds there are dogs with high activity versus low activity needs.

For example, a Jack Russell Terrier is a small breed that is not suited to live on a very small property, or indoors. Jack Russells have very high activity needs as a breed, and not having enough exercise will result in these dogs developing all sorts of behavioral problems, ranging from destructive behavior to aggression. Other small breeds which are high activity include most of the terriers; Foxies, Parsons and Border Terriers included.

Small dogs with lower activity needs include Yorkies, Maltese Poodles, Bichon Frise, Miniature Daschunds and Pekingnese. Don’t forget that these dogs also need to be walked and exercised but to a lesser extent than their high activity counterparts.

Some of the highest activity breeds regardless of size include; Border Collies, German and English Pointers, Belgian Shephards, Australian Shepherds, Australian Cattle Dogs, Spaniels, Dalmations,  Weimaraners and Airedale Terriers.

It would be a very bad idea to get any of these dogs unless one can put the intensive time and energy into training and exercising them.

Dogs Can Sniff Out Human Diseases

We all know that dogs have an amazing sense of smell, and we have utilized this fact for many years in tracking and drug detection. Dogs smell in parts per trillion, to illustrate this to you, if you put a drop of blood in 3 Olympic-sized swimming pools; a dog would smell this blood.

Recent studies have shown that dogs can be trained to sniff out cancers of the lung, breast, skin, bladder and prostate. In a 2011 study, lung cancer was identified with a sensitivity of 71% and a specificity of 93%.[1]In another study 66 patients referred to a urologist were selected, 33 confirmed with prostatic cancer and 33 controls. Belgian Malinois Shepherd Dogs picked 30 of the 33 positives correctly. [2]

Other amazing medical applications of dogs’ sense of smell include their increasing use as service animals for people with diabetes, where they can detect fluctuations in blood sugar (dangerous for diabetic patients) and alert them even before they feel symptoms.

Apparently dogs have also been documented to detect epileptic seizures 45 minutes before they occur. Scientists still have no idea how this occurs.

Why We Ask You Not to Feed your Dog Bones (and remove any other dangerous ingestible objects from your pet’s reach)

This afternoon Dr Keri removed a corn cob that was lodged in a very sick dog’s intestines. More common objects we have to remove surgically from dog’s intestines include bones (especially ones that are small enough to swallow; such as vertebrae – skaap en beesnek- and chicken bones) as well as small toys strings, and stones.
The blocked object causes the blood supply in the affected segment of intestine to be compromised, and if not removed, these dogs will die from dehydration and sepsis due to infection and toxin release into the dog’s body from the dying gut wall. If a dog is presented to us showing the symptoms of a foreign body intestinal obstruction, we can sometimes actually feel the object in the abdomen, but often we need to take x-rays to try and visualize the object to differentiate an obstruction from more common causes of vomiting.
A pet insurance company in the US called VPI, received 2000 claims in 2010 of foreign body ingestion in dogs. Most commonly isolated were bones, stones, sticks, towels and rocks but here is a list of more unusual items that vets removed from dog’s intestines during that year. (From
