You see them everywhere: the “lost dog” signs stapled to telephone polls, the “missing pet” ads in the daily newspaper. The fact is, losing a pet — even just for a short period — happens to even the best of owners.

According to numbers from the ASPCA, approximately 36 percent of the 3.9 million dogs that enter animal care shelters in the United States enter as strays that were separated from their owners. That’s a lot of lost dogs!

Fortunately, technology exists to help you find your pet in the event that he ever becomes lost. Microchipping your dog, along with outfitting him with a collar and up-to-date ID tags, will go a very long way toward helping you reunite with your beloved pet.

Because microchipping is new to some people, and the technology hasn’t caught on everywhere, many people have questions when it comes to this topic. Here are some answers to the questions dog owners might have about microchipping.

1. What is a microchip?

A microchip is a small electronic chip enclosed in a glass cylinder — so tiny that it’s about the size of a grain of rice. The microchip is inserted under your dog’s skin via a hypodermic needle and is activated by a scanner that is passed over the microchip. Once it’s activated, the microchip emits a radio frequency and displays information that can help recover your dog in the event that he becomes lost, including a registration number and the phone number for the registry of the particular brand of microchip.

2. Will a microchip hurt my dog or get lost in his body?

Getting a microchip inserted via a hypodermic needle feels pretty similar to any kind of injection — a quick pinch and it’s done. The microchip is inserted beneath the skin and begins to bond to the surrounding tissue within 24 hours, preventing it from moving, according to the Humane Society of the United States. There’s a small chance that the microchip can move slightly, but it won’t get lost in your dog’s body.

3. What kind of information does a microchip hold?

Microchips only contain identification numbers that are generated by the registry of the particular brand of chip.

4. Can a microchip replace a collar and ID tags?

No! Think of microchipping your dog as added protection. A collar and up-to-date ID tags are still a great bet for recovering your dog if your average person finds him wandering around, especially if that person doesn’t have access to or doesn’t know about microchips. Plus, like most technology, microchips aren’t foolproof. According to the HSUS, universal scanners can detect the presence of a microchip, but might not be able to read the information on it. And if an animal shelter volunteer or vet clinic staff doesn’t use the scanner properly, it might not detect the microchip.

5. Is there a central database that registers microchip information?

Not really. Each brand of microchip maintains its own database. Fortunately, though, microchip scanners display the name of the microchip’s manufacturer when the microchip is read.

To help users find out microchip information more easily, the American Animal Hospital Association launched the Universal Pet Microchip Lookup Tool in 2009. entering the microchip ID into the search bar, users can find out which manufacturer is associated with the ID, and can then contact the manufacturer to find out owner information. According to the American Veterinary Medical Association, the likelihood that an pet can’t be identified from his microchip is very low.

6. What happens to the information on my dog’s microchip if I move?

If you change addresses, you must contact the company that registers your dog’s microchip and update your information.

7. Where can I get my dog microchipped?

Most veterinary clinics provide microchipping services. Some pet-supply stores and animal shelters also provide microchipping events.

8. Are there any health concerns associated with microchips?

Some news reports have linked microchips with cancer; however, the AVMA states that the chance of a pet developing cancer because of a microchip is “very, very low.”

9. Will a microchip really help to recover my dog if he gets lost?

Yes! According to the AVMA, a study of more than 7,700 stray animals at shelters showed that dogs with microchips were returned to their owners over 52 percent of the time; dogs without microchips were only returned to their owners 21 percent of the time. Of the dogs that weren’t returned, most of the time it was because the owner information in the registry database was incorrect, or the chip was never registered. So if your dog is microchipped, be sure to register his information, and keep it current!

When you think about grooming a dog, you probably consider bathing him, brushing his coat, even cleaning those floppy ears, but its a good idea to give dogs a pedicure every few weeks as well. If youve never trimmed a dogs nails, ask for some help from a more experienced person, and keep these instructions nearby.

1: Stay Sharp

ThinkstockA few different tools are available to help you trim a dogs nails, including those that resemble miniature pliers and those with replaceable sliding guillotine blades. Use whichever model makes you and the animal most comfortable, but be sure to replace the blade frequently to make the job easier and prevent the dog from feeling any discomfort.

2: Pull Their Legs

Dogs are often pretty cooperative when it comes to having their nails trimmed, and those who were handled often as puppies are even more likely to comply. Still, you may need to work a little to keep the animal still. If youre working alone, have the dog sit or lie down on the floor or examining table, then trim the nails, one paw at a time.

3: Pull Their Legs, Part II

If youre grooming a larger dog or if the animal is apprehensive, have someone sit him down and hold out his paw, then get to work with the clippers. Have your helper scratch behind the dogs ears to reassure the animal and help move things along a little more quickly.

4: Take the Edge Off

Remember that you should only remove the very end of the dogs nails. You may be tempted to trim off all of the excess, but that would be a mistake. In dogs, the quickthe nerve endings and blood vessels inside the nailcontinue to grow as the nail grows. That means long nails must be trimmed bit by bit, over weeks or months, until the quick gradually recedes. Because its so difficult to see the quick in dogs with dark nails, youll need to look at the nail straight on (see diagram below)and keep trimming until you see a small dark circle. If you accidentally clip too far and the nail begins to bleed, apply pressure to the tip of the nail or dip the nail in a bit of styptic powder, then make sure the animal is kept inactive for a short time.

5: Thank Them Very Much

Give the dog a treat or a pat on the tummy to thank him for his cooperation, and things should go at least as well the next time around.
