Dogs may growl to express pleasure while playing, and they sometimes growl when they are stressed. They may think someone’s going to take one of their resources (like food), or perhaps they feel endangered by the approach of someone they don’t know or feel uncomfortable around. Can you tell the difference?

The survival rate for dogs in the hospital who stop breathing and undergo CPR (cardiopulmonary resuscitation) is low. Fewer than 6 percent make it out alive. In an effort to improve the odds, researchers participating in an initiative known as RECOVER— Reassessment Campaign on Veterinary Resuscitation—combed through almost 1,400 studies to ascertain which methods work best.

Looking for a new type of environmental enrichment for your dog? Consider enrolling your pet in the Dog Scouts of America, an organization where canines can earn merit badges for mastering such skills as agility and “nose work.” The organization also stresses the importance of humane education, positive training (punishment-based training is not allowed), and community involvement. For instance, some troops have hosted fundraisers to purchase Kevlar vests for K9 officers and animal-size oxygen masks for local fire departments.

Most dogs are easy enough to get a pill into, even on a regular basis if need be. You simply make a “meatball” out of some wet dog food or something else soft, like deli meat or cheese, and your dog will end up reminding you about his medication after a while. You just have to make sure with the veterinarian that whatever food you use to wrap the pill doesn’t contain ingredients that are bad for the condition you’re treating.

Q: What exactly are Rally-O classes? There’s one near me, and one of my friends wants to sign our dogs up.

A lot of people believe that a cool, moist nose is a sign of good health in a dog and a warm dry one means something’s wrong. But that’s not the case.

Q: My son realized that his 8-year-old golden retriever lost vision in one of her eyes. She was diagnosed with something the doctor called pigmentary uveitis. The veterinary ophthalmologist indicated that the pressure in her eye was very high, causing pain, and recommended removing the eye. My son followed the recommendation, but what can be done to prevent this wonderful dog from getting pigmentary uveitis in her other eye?  

One thing new research makes clear. If your dog has swallowed a non-food item and is showing signs of not feeling well—vomiting, lethargy, lack of appetite, diarrhea, inability to void solid waste—you should not delay getting him to the veterinarian’s office. Investigators went through the records of dogs who had been taken to the hospital because they had ingested a foreign body and were treated with conservative medical management rather than surgery. The result: those dogs who were brought in more than one day after their symptoms started were not as likely to have successful outcomes. They more frequently ended up needing an operation.

Ingestion of a single penny minted after 1982 is enough to kill a dog weighing fewer than 50 pounds. That’s because pennies minted after that year have a copper coating but are almost 98 percent zinc, which is highly toxic to dogs. Lest you think zinc poisoning is uncommon, the Animal Poison Control Center (888-426-4435) reports more than 4,000 cases of zinc toxicity every year. Pennies are usually the cause. But dogs, being the indiscriminate eaters they are, also swallow other zinc-containing items, including batteries, staples, nuts and bolts, zippers, board game pieces, jewelry….

Sure, you may love the look of a gleaming hardwood or tile floor, but perhaps your dog equates stepping onto such a surface with the way one might see a treacherous foray onto the ice in slippery shoes.
