How to Choose a Healthy Pure-Bred Puppy

You made the decision to get a puppy and did your research to find the perfect breed -- the one that will match your family’s temperament, energy level, and personality. But how do you find the best breeder to get a healthy, well-adjusted puppy? WebMD asked Lisa Peterson, the director of club communications for the American Kennel Club and a longtime breeder of Norwegian elkhounds, for some advice.
 
Q: There are ads for puppies in the newspaper, on the Internet, and, of course, there are those adorable puppies in the pet stores. Where’s the best place to buy my purebred puppy?
A: Breeders advertise in a variety of ways, including ads on the Internet, in newspapers, and their own web sites. Those are all good places to start, but they are also places you can run into a lot of trouble if you don’t do your research. You can go to our web site, www.AKC.org, to look for the parent club of our breeds. We list breeder referrals for all these clubs and they can put you in touch with breeders across the country.

Q: I’ve heard dogs in pet stores usually come from puppy mills. What are those and are they bad?
A: Most puppies in pet stores come from licensed commercial breeders. Those breeders that register with the American Kennel Club are inspected by us for care and conditions, record keeping, and other things.
There are more than 30 dog registries today. But the AKC is the only nonprofit registry and the only registry that inspects our breeders and mandates that the puppies be raised in humane conditions.
The term puppy mill really describes a kennel with filthy conditions, usually where there are too many dogs to care for properly. Many times these places are unlicensed because they sell directly to the public via the Internet. These are not your well inspected, licensed facilities. We have inspected some puppy mills and some were suspended by us.

Is Grain-Free Really Better for Dogs?

Doesn’t it seem like “grain-free” dog diets are taking over the pet food aisle? I’m surprised at just how omnipresent they’ve become. While there is nothing inherently bad about grain-free dog food, I worry that owners are being led to believe that grain-free foods are necessary for dogs. This is simply not the case.

Let me first say that there are times when a particular individual will benefit from a grain-free diet. For example, a dog who is allergic to wheat should obviously not be fed a food containing that type of grain. The question I want to look at, however, is, “Are there any benefits from going grain free for healthy dogs?” I believe the answer is “no” and that the popularity of grain-free diets is based on a couple of basic misunderstandings.

First of all, “grain free” is not the same as “carbohydrate free.” Starch, a type of carbohydrate, is essential to the formation of dog food kibble. Therefore, if you are feeding dry dog food, it has to contain a certain amount of carbohydrates. A quick look at the ingredient list will reveal the presence of potato, sweet potato, tapioca, or other carbohydrate sources. The phrase “grain-free” is not a substitute for “carbohydrate-free” or even “high-protein,” which is what most owners who buy these products seem to be looking for.

Contrary to what you might have heard, dogs do have all the digestive enzymes needed to break down, absorb, and utilize nutrients from grains. I’ve heard proponents of grain-free diets argue that dog saliva does not contain the enzyme amylase, which is needed to break down carbohydrates from grains. While it is true that dogs don’t make salivary amylase, their pancreas does make the enzyme, and since dogs tend to swallow large chunks of food without chewing, the need for salivary amylase is questionable. The lining of the dog’s small intestine also produces brush border enzymes that are responsible for much of the carbohydrate digestion.

Don’t get me wrong. Even though dogs digest carbohydrates quite well and grains are a healthy source of carbohydrates for most dogs, pet food manufacturer can overdo it. Carbohydrates are cheaper than animal-based sources of protein, so the financial lure of maximizing the former while minimizing the latter is hard for some companies to resist. If what you’re looking for is a low-carb, high protein dog food, you need to be looking at the guaranteed analysis on the back of the bag rather than the marketing hype on the front.

A food’s carbohydrate percentage does not have to be included in the guaranteed analysis, but it’s quite easy to estimate. Add up the percentages for crude protein, crude fat, crude fiber, moisture, and ash and subtract the result from 100%. The result is a ballpark figure for the food’s carbohydrate percentage. If a number for ash is not provided, use 6% as an estimate for dry food and 3% for canned.

If you want to compare dry and canned foods, you’ll probably need to do a bit more math because most companies report their guaranteed analysis on an as fed rather than dry matter basis.

  1. Find the percent moisture and subtract that number from 100. This is the percent dry matter for the food.
  2. Divide your carbohydrate percentage by the percent dry matter and multiply by 100.
  3. The resulting number is the carbohydrate percentage on a dry matter basis.

Analyzing a food’s guaranteed analysis is not as simple as buying into the buzz around grain-free, but the work will let you make an informed decision about what to feed your dog.

How to Feed Older Dogs

Nothing beats a good, old dog. The relationship between canine senior citizens and their owners is exceptionally deep and multifaceted. Good nutrition can help keep this relationship going strong for as long as possible.

Definitive guidelines regarding what constitutes the best diet for older dogs do not exist. Owners and veterinarians need to work as a team to assess every dog’s individual nutritional needs and make appropriate dietary choices.

The first step is to screen the dog for disease. Nutritional management plays a role in the treatment of many illnesses that are commonly diagnosed in older dogs (e.g., chronic kidney disease, diabetes mellitus, some types of cancer, and heart disease). If a dog has a nutritionally responsive disease, he or she should eat whatever diet is recommended for dogs with that condition. Considerations based on age take a back seat in these cases.

Owners have a lot more leeway when feeding healthy, older dogs. Senior dog foods occupy a lot of shelf space in stores, but they can be quite different from one another. Picking the right product is very important. For example, most senior dog foods are somewhat lower in fat than are traditional, adult foods. Because most older dogs require fewer calories than they once did, reducing the fat content of their diet can help prevent obesity. A lower fat food is perfectly appropriate if your older dog does, in fact, have a tendency to gain weight. On the other hand, if you have a skinny old dog who struggles to maintain his weight, a low fat dog food will make the problem worse rather than better.

Older dogs can also have trouble maintaining their lean body (muscle) mass, and some senior dog foods contain less protein than those designed for young adults. I assume this choice is based on the misguided assumption that lower protein levels will protect an older dog’s kidneys from damage. In fact, many dogs actually need a little more protein in their diet as they age if they are to maintain a healthy lean body mass. Avoiding excess protein is important if a dog is in kidney failure, but research has shown that feeding reduced protein foods to older dogs “just in case” is a mistake.

Look for the following characteristics in diets designed for older dogs:
  • High quality ingredients to maximize digestibility and nutrient absorption and reduce the formation of potentially damaging metabolic byproducts
  • Antioxidants (e.g. vitamins E and C) to promote immune function
  • Fish oils or other sources of omega-3 and omega-6 essential fatty acids to maintain brain, skin, and joint health

Because of the variability in senior dog foods, there is no guarantee that the first one you try will be the right one for your dog. If after a month or so on one diet you are not pleased with your dog’s response, try another… and another… and another, or ask your veterinarian for help picking out the right food for your dog.

What To Do When a Dog Stops Eating

Most dogs love to eat, which is why a meal that has been left untouched immediately raises concerns. An almost endless list of problems can cause dogs to go off their food — some are trivial but others are potentially life-threatening.

Determining whether immediate action or watchful waiting is the appropriate response can prevent canine suffering and unnecessary veterinary expenses. When your dog stops eating, follow these five steps.

1. Think about the last few days

Hindsight often really is 20:20. Now that you know something is up with your dog, think over the last few days. Did something occur that could be responsible for your dog’s lack of appetite, for example a change in diet or a “mysteriously” overturned trash can? Has your dog’s appetite been somewhat reduced recently? Have you noticed any other symptoms (e.g., lethargy or loose stools) that may be related to what’s going on?

Make note of when your dog’s first symptom developed. When dogs are going to get better on their own, improvement will usually be noted within 24-48 hours, but you need to know when that clock started ticking. If skipping breakfast is honestly the first sign of trouble and your dog seems to feel fine otherwise, waiting a day or two to call the vet is perfectly reasonable. If, however, a loss of appetite is just the latest in a series of symptoms that have developed over the course of a few days (or longer), the “wait and see” train has already left the station.

2. Ask other people in the dog’s life if they’ve noticed anything

Unless you are the only person looking after your dog, ask his or her other caretakers whether they’ve noticed anything unusual over the last few days. Perhaps your spouse pulled the dog out from under a bush with something “icky” in his (the dog’s!) mouth on a recent nightly walk, or your neighbor’s dog who routinely comes over to play is ill.

3. Examine the dog

Perform a “quick and dirty” physical exam on your dog. Gently push on his or her belly. It should be soft and your dog should not react in pain. Look for evidence of diarrhea in the fur around the rectum or vomit around the mouth. A dog’s gums should be pink (unless they are pigmented) and moist. Dry or pale mucous membranes can be a symptom of dehydration and/or other serious conditions. If you find anything worrisome on your physical exam, call your veterinarian immediately.

4. Inspect the food

Whether you feed a commercially prepared or homemade diet, something might be wrong with the food itself. This is especially true if you just fed the first meal out of a new batch of food, or if the bag, can, etc. has been open for quite awhile. Look at and smell the food. If anything appears “off,” try feeding your dog again from a different lot of food. I don’t recommend making a wholesale diet change at this point, since it will be difficult to determine if a dog is not eating because he or she does not like the new food or is continuing not to feel well.

5. When in doubt, talk to your veterinarian

It’s always better to err on the side of caution. Problems caught early are easier (and cheaper!) to resolve.
