Q: Our dog, Pearl, seems to prefer my wife to me, and that hurts my feelings. Do you know why? Can I do anything to convince Pearl to like me more?

A: A few possible reasons come to mind. Does your wife feed Pearl? Does she spend more time with her? Does your wife greet Pearl warmly and cuddle her more than you do?

Another possibility is that you tease Pearl, and she doesn’t trust you. Scientists conducted an intriguing study on this topic and concluded that when dogs discover that certain people tease or mislead them, they no longer trust them.

In their 50-dog experiments, researchers hid food in one of two containers, pointed to a container, and recorded which container each dog chose.

In phase 1 of the study, a scientist pointed to the container with food, and the dogs opened that container. In phase 2, the same researcher showed the dogs what was in both containers and then pointed to the empty one.

In phase 3, the same person pointed to the container with the food, but by this time, the dogs did not trust that person’s signal, so only 8% of them opened the container.

However, when a new scientist conducted phase 3, all the dogs opened the container with the food, presumably because they trusted this new person who had not misled them.

Yet another possible reason for Pearl to prefer your wife is that she perceives her to be more competent than you. In a recent study of 74 dogs, scientists showed them two people, both actors, trying to remove the lids from transparent containers, some of which contained food.

One person was adept at removing the lid, while the other was incompetent. Dogs preferentially approached and spent time with the competent person — but only when the transparent container held food.

Surprisingly, only the female dogs preferred the competent person, while the males showed no preference.

One of the researchers explained this difference by saying, “Female superiority in the social cognitive domain has been reported across many mammalian species, including humans.”

In an earlier study, these researchers had learned that dogs avoid people who decline to help their owners remove an object from a transparent container. If that sounds like you, be sure Pearl sees you helping your wife around your home. If your wife feeds Pearl, ask to take on that responsibility at least half the time.

These studies show that dogs prefer competent, helpful people who don’t mislead or tease them. If that’s already who you are, consider taking Pearl to an obedience or agility training class to enhance your bond.

Q: I am confined to my home with a terrible case of pinkeye. I can’t have visitors because pinkeye is very contagious to other people.

Thank goodness my cats love to snuggle. But, I’m worried they might catch my pinkeye. Is that possible?

A: No. Human pinkeye, or conjunctivitis, is caused by many viruses and bacteria that are highly contagious to other humans.

Fortunately, though, the viruses that cause conjunctivitis in humans are not transmitted to cats, and the bacteria very rarely spread to cats.

Cats develop their own version of conjunctivitis, which is rarely transmitted to humans.

So, feel free to snuggle your cats as much as you like. In the opinion of many people, snuggling with cats promotes human healing.
