The first test looks at short-term memory. You may observe failures in your own short term memory in situations when you ask for a phone number from an operator and correctly dial it immediately, meaning that the number is stored in your short-term memory. However, when you get a busy signal and hang up to dial the number again, you often find you’ve forgotten the number, since short-term memory fades quickly.
The test requires an average-sized room that doesn’t have a lot of furniture or other material cluttering it. You need a tidbit of food that has no strong odor (otherwise, Lassie’s scenting ability will bias the results). If Lassie will not reliably sit and stay on command, have a helper present to hold her.
To start, place Lassie on a leash, and have her sit in the center of the room. While she watches you, show her the treat, then, with a great exaggerated show (but no sound), place the tidbit in a corner, making sure that she sees you put it down. Lead her out of the room, walk around in a small circle, and then bring her back to the center of the room. Leaving the room and returning to it should take no more than about fifteen seconds. Slip the leash off the dog, and start the stopwatch. Score as follows:
The next test looks at long-term memory, which is relatively permanent and long lasting. Give this test immediately after the preceding test. The set-up is identical to the short term memory test. Make sure, however, that you place the tidbit in a different corner than the one you used for the short-term memory test. Take Lassie out of the room and keep her out of the room for five minutes. Then return her to the center of the room, slip off the leash, and start the stopwatch. Score as follows:
This next test looks at environmental memory, which simply means how well your dog remembers the world around her. While
Lassie is out of the house, rearrange the furniture in a room that is familiar to her. For example, you could bring a few additional chairs
into the room, move a large piece of furniture toward the center of the room, place a coffee table in an odd corner, move a side table to the center of the room, or create several other obvious disturbances of the usual pattern of furniture placement. Try to make sure that at least five things are obviously different in the room. Then bring Lassie into the room and start your stopwatch while you stand quietly. Score as follows:
The final test involves alternate choice memory, or how well the dog remembers one of several possibilities. For this test, you need three identical, empty tin cans or plastic cups. Rub the inside of each with the tidbit of food that you will be using as bait, so that Lassie can’t use smell to guide her choice. Next, while she watches, show her the empty cans and arrange them in a row upside-down with about one foot (30 cm) between each. With exaggerated movements, show her the treat, then lift the middle can and place the treat under it. Slip the leash off and let her go. Whether she actually gets the treat or not by knocking over the can is irrelevant for this test, but note the attention that she pays to each can. Score as follows:
Add the scores from the four tests. If your dog scores 17 to 20, her memory is extremely good. Scores from 13 to 16 are above average, while 9 to 12 are average. Scores of 6 to 8 are borderline, while scores of 5 or less would place a dog in the bottom 10 percent of all dogs.
Although it is simply fun to know how good your dog’s memory is, it is also a useful thing to measure your dog’s memory when she is a healthy adult. You will then have a score to use as a reference to see if your dog’s memory is declining as she grows older.
If your dog’s memory is good, it will be easier for her to learn. If your dog’s memory is bad, it will be easier for her to forget that she was pinched or pulled by a particular child. She will also be less likely to remember that she should be still bearing a grudge against you for a late dinner or a missed walk-or that last trip to the vet.
