The information available in canine urine is astounding. From a proper sniff, dogs can learn about the sex, reproductive status, diet and stress level of dogs who have been there before. Urine is used to communicate about territories, to mask the smell of other dogs, to detect females who are likely to be reproductively receptive and to compete with other individuals. It’s no wonder that our canine friends find urine so compelling that they are irresistibly drawn to it. As anyone who has spent even a little time with dogs knows, urine sniffing is a favorite pastime.

A recent study called “Length of time domestic dogs (Canis familiaris) spend smelling urine of gonadectomised and intact conspecifics” was conducted to investigate whether gonadectomy (being spayed or neutered) affects urine-sniffing behavior. Since gonadectomy has significant impacts on body chemistry, it has long been suggested that it disrupts the flow of information available through urine that dogs have evolved to detect over many generations.

Researchers tested the affects of gonadectomy in urine sniffing by recording how long dogs sniffed urine from intact versus gonadectomized individuals. They found that dogs spent more time sniffing urine from spayed or neutered dogs than from intact ones. One possibility is that the dogs are spending a longer time sniffing such urine because they are trying to figure out the information it contains. Because it may have a combination of chemicals that is different than the range of compounds that the dogs have evolved to understand, it may be harder for them to make sense out of it.

Interestingly, this study contradicts the findings of Lisberg and Snowdon, whose 2009 paper also analyzed the investigation patterns of unfamiliar urine and found that dogs spent more time sniffing urine from intact dogs than from gonadectomized ones. One possible explanation for the difference may be that for the current paper, the dogs were tested indoors, but for the 2009 paper, the study took place outside. (Fewer distractions inside may also explain an average sniff length of nearly 13 seconds in this paper compared with just over 5 seconds in the older study.) Another difference between the results of the two studies is that the recent research found no difference in sniffing time related to what kind of dog was doing the sniffing (male or female, intact or gonadectomized) but Lisberg and Snowdon found that neutered males and intact females both spent more time sniffing urine from intact males than from neutered males.

More research is definitely needed if we want to understand the complicated behavior of urine sniffing, which may involve many interactions between environment and individual traits of the dogs—both those who are the sources of urine and those who sniff if. Research is time intensive and can be costly, which is why I’m so impressed by this particular study. It was conducted in a single home in which the 12 dogs recruited to be sniffers all live, there was no funding source for the study and all of the urine in the study came from out of state to insure that the urine came from unfamiliar dogs. Kudos to the authors for taking the initiative to conduct a cool and clever experiment!

It sounds trivial to say it, but dogs and cats are very different animals. The experience of living with individuals of these two species is not the same in many ways. I know I am generalizing here and ignoring the many exceptions, but the typical cat is more independent that the typical dog, and usually more aloof. (Again, I know there are dogs who lean towards the standoff-ish, and cats who are clingy and constantly affectionate, but that’s not the most common way for members of those species to be. Think of it this way—it remains true that men are generally taller than women even though there are certainly individual women who are taller than individual men.)

My point here, and I’m sure you’re glad I’m getting to it, is that if someone has experience with cats, they may acquire perspectives and skills that are different from those acquired by people who spend all of their time with dogs. (It should go without saying that I have no problem with anyone spending all of their time with dogs!)  Those skills and perspectives can be very useful with certain dogs, though I’m not necessarily referring to dogs who are more cat-lie in any way.

The dogs who benefit most from the knowledge of cat-savvy people are those who are shy, fearful or nervous. People who know cats well are completely on board with the fact that you can’t push or force a cat to be social with you. (It’s unwise to push or force a dog, either, by the way, but many dogs are easier to convince to engage with us than cats are.)

With cats, it is always wise to take it slow, let them come to you and ignore them until they show an interest in you. That is also true of fearful dogs, but many people who come into contact with a dog who is afraid try to cajole the dog into approaching, or try to lure the dog with toys or treats. People with cat experience are far less likely to try to take shortcuts like this, to the benefit of the dog in question. Cat-savvy people are used to the idea that you have to accept the animal on his own terms and to be patient. To be fair, many dog lovers also know this really well, but I find that it is almost universal among people who have spent a significant amount of time with their feline friends.

I was recently reminded of the wonderful way that many cat lovers have with shy, nervous or fearful dogs when my friend Betsy came over while I was watching a dog of that description. I told her that the dog was very sweet, though easily scared by new people, and that the best thing to do was to toss her some treats and then ignore her. Betsy did exactly that, and within minutes, I took this picture of a very happy dog (the lean one on the left with a tail wagging fast enough to look blurry) enjoying her new human friend. Throughout their initial interaction, Betsy always let the dog control the pace of their progress. She never pushed too hard to pet the dog or encouraged the dog to approach. She just waited and let the dog do what felt comfortable.

Do you have cat experience that has helped you in your interactions with dogs?
