The German shepherd is a breed of many talents, including scent work. Of around 1,000 known genes for receptors (special cells that are activated by odours), about 40 per cent are non-functional pseudogenes meaning they do not actually code for odour receptors in the nose. In addition to seborrhea, they are also prone to hip dysplasia, digestive problems and others. Not to be outdone, polar bears have been known to detect seals up to 65 kilometers (40 mi) away.

In these terms, mice have olfactory bulbs 200 times the size of humans, while those of dogs are 40 times larger. The science behind what actually makes a smell truly horrific is actually quite complicated. Since the olfactory bulb area in the bear's brain is five times larger than the human brain, bears have the best sense of smell of any animal in the world. But now a review of the latest evidence, published in the journal Science, challenges this idea. 6. He based this distinction on two main pieces of evidence: the comparatively small size of the brains olfactory bulbs (the neural structure involved in smell) relative to total brain volume, and the observation that odour has less influence on human behaviour compared with other species. Besides, it's common knowledge that polar bears and silvertip grizzlies have exceptionally acute senses of smell. Due to their incredible sense of smell, honeybees are as good as or even better than the dogs which are normally used for such purposes.

Hens, which can smell danger before the human can. Beside having an amazing sense of smell, dogs are also smart animals. This is a little dog with a small mouth and a lot of teeth. The research suggests that our much-maligned nose and all the associated neural apparatus involved in smell perception is not really the issue. Writing in 1879, Broca divided mammals into those for whom smell is critical in day-to-day behaviour (such as dogs and rodents) and those for whom it is not (mainly primates including humans). Similarly, animals have different senses. Our sense of smell plays a major, sometimes unconscious, role in how we perceive and interact with others, select a mate, and helps us decide what . For example, new studies suggest that pseudogenes may in fact have some regulatory function on other genes involved in smell reception and that the proportion of functional to non-functional genes across species is neither a reliable predictor of olfactory prowess nor of differences in visual abilities among primates. You can make a spray solution from mint herb and other strongly scented plants like rosemary and water, and spray it in the needed areas or you can grow them around your garden to keep your dog away from trampling your favorite plants.
