best dog food for older dogs losing weight

Best Dog Food For Senior Dogs

A long life is the result of good genes, good care, and good luck. While a few four-leaf clovers never hurt anyone, chances are its a little late to worry about good genes once youve welcomed a dog into your heart. That leaves good care as the one thing you can control now. And a big part of good care is good nutrition.

However, there are issues when it comes to feeding your senior dog. Neither the Association of American Feed Control Officials (AAFCO) nor the National Research Council have determined official dietary requirements for aging dogs. Its partly because senior dogs vary so much in their individual needs. That may explain why commercial foods for seniors vary so widely in nutrient levels.

Nobody expects you to be a nutritionist just to pick out a bag of dog food. But you should be aware of just a few important factors that apply to most senior dogs. This will help you choose the best dog food for your senior dog.

Dont Restrict Protein

This matter is widely misunderstood. Many people still believe senior dogs should eat less protein. We now know the opposite is true. Healthy seniors need more protein, not less, in order to fuel muscle. Loss of muscle mass is a major problem in older dogs. Some seniors lose so much muscle they can no longer walk unassisted.

Older dogs need about 50 percent more protein to maintain muscle mass compared to younger ones. But, diets formulated for adult maintenance diets often dont have enough protein to satisfy these needs. Veterinarian Ernie Ward, founder of the Association for Pet Obesity Prevention, recommends 28 to 32 percent protein on a dry-matter basis for healthy older dogs, especially in those cases where weight loss is needed.

Consider Calories

Younger seniors tend to be overweight. But, very old dogs tend to be underweight. A 2011 study found that calories in senior foods varied widely, ranging from 246 to 408 calories per cup. So, the same senior food may be a great choice if your dog needs to lose weight. But it may be a bad choice if they need to gain weight.

Dont forget that the time to consider calories is well before old age sets in. Two benchmark studies conducted by major dog food companies Purina and Waltham both found that restricting calories throughout life improved longevity and reduced illnesses. Essentially, good care for senior dogs starts in youth.

Feed For Organ Health

Other factors to consider are senior dog health problems such as heart and kidney disease. For both conditions, youll want a low-sodium food. But, that same 2011 study found that sodium levels in senior foods ranged from 33 to 412 mg/100 kcal. For kidney disease, youll want low phosphorous, but thats not even mentioned on any label. The 2011 study found phosphorous levels varied by threefold in the senior foods they examined, but were on average higher than their representative adult maintenance food.

Prescription diets are available for heart, kidney, and other diseases that take into account these nutritional needs. However, even those foods may have wide ranges of nutrients. Any dog food manufacturer should be able to provide these numbers to you on their website or with a simple phone call. While youre at it, ask them about the credentials of the people formulating their foods. If they cant provide either, thats clue number one that you should find another product.

Add Supplements

Some senior foods include supplements such as glucosamine and chondroitin in an effort to combat osteoarthritis. Unfortunately, the evidence that these supplements actually work is limited. However, they wont hurtexcept maybe your wallet.

On the other hand, omega-3 fatty acids probably play an important role in senior diets because they may help combat both osteoarthritis and especially cognitive losses. If you are adding your own to your dogs diet, aim for the amount of EPA and DHA combined to be in the range of 700 to 1,500 mg. Build up starting at the low end and cut back if your dog has any diarrhea or vomiting.

Theres probably more to the recipe than simply EPA and DHA, however. Research conducted at Purina tested Beagles between the ages of 9.5 and 11 years of age that were fed either a standard diet or one supplemented with antioxidants, B vitamins, fish oil, and L-arginine for six months. The dogs fed this Brain Protection Blend performed significantly better on a series of mental tasks, especially the more difficult ones, compared to the dogs not receiving the blend. The tasks involved determining which one of several shallow wells contained food when the cue was a marker either next to it, near it, or displaced at an angle; or seeing how well they did on a task requiring them to discriminate right, left, and center, and then relearning which side was correct in order to receive a reward.

Make Food Palatable For Senior Dogs

There are practical aspects of feeding your dog to consider, too. Senior dogs may have dental problems that make chewing difficult or uncomfortable. These dogs should first be treated for whatever problem they have, but if that is impossible or unsuccessful, consider wetting their food or feeding them canned or soft food. Simply feeding a smaller kibble size may help if youre feeding dry food.

Senior dogs may be uncomfortable bending down to the food bowl or standing for long periods to eat. Try serving their meals on a raised platform or encourage them to eat lying down.

Very old dogs often lose their appetite. Warming the food can increase its aroma and may help stimulate the appetite; cooling it may make it less nausea-inducing in queasy dogs. At some point you may have to abandon your goal of a healthy balanced diet and just feed him whatever he will eat. The wait until hes hungry enough tactic doesnt work in seniors because their hunger mechanism may not be working correctly. Besides, its a little late to be worried about spoiling himand even if you do, doesnt he deserve it?

Why Your Dogs Losing Weight and What to Do

Its normal for a dogs weight to vary a little bit over time. If you change their diet to one that isnt to their liking, theyll probably lose a few pounds. Or maybe they are staying inside more during the winter; in this case, theyll probably gain a little.

But what about a dog that keeps losing weight and you dont know why? Unexplained weight loss can be the first sign that a health problem is brewing.

Why Is My Dog Losing Weight?

Weight loss in dogs has many causes. Problems with a dogs diet, environment, and health could all be to blame. Here are a few of the most common causes of unexplained weight loss:

• A problem with their food: Dogs may eat less when there is something they dont like about their food. A change in diet may be to blame, or perhaps a large bag of food has started to go bad before your dog has finished it. Feeding too little or giving your dog low-quality dog food can also lead to weight loss.

• Stress:A dog thats anxious or stressed may find it hard to relax and eat because they feel like they always need to be on alert.

• Exercise: Dogs that start exercising more but dont take in more calories will lose weight.

• The environment: Dogs require extra energy to stay warm when they spend lots of time in the cold. Conversely, hot temperatures can reduce a dogs appetite.

• Reproduction:Pregnancy and lactation (nursing puppies) put extra nutritional demands on dogs. If they dont take in more calories, they will lose weight.

• Dental disease and other oral problems: Any problem that makes chewing and swallowing painful or difficult will discourage a dog from eating.

• Intestinal worms and other parasites: Parasites get their nutrition from their hosts, which can lead to weight loss in dogs.

• Cancer: Cancer cells use energy to grow and divide, and this means that the energy is not available to the dog, so they often lose weight. Cancer can also directly affect a dogs digestive system and appetite.

• Gastrointestinal (GI) disorders: Problems that affect the functioning of the digestive tract can reduce a dogs appetite or their ability to digest and absorb nutrients. Inflammatory bowel disease, lymphoma, adverse food reactions, or partial intestinal blockages could be to blame.

• Nasal problems: Any condition that affects a dogs ability to smell their food can lead to a reduced appetite.

• Diabetes mellitus: The changes in glucose metabolism seen with diabetes mellitus frequently lead to weight loss in dogs, even when they have a good appetite.

• Exocrine pancreatic insufficiency (EPI): When dogs have EPI, they dont produce enough of the digestive enzymes needed to break down food and absorb nutrients.

• Infections: Bacterial, viral, or fungal infections can directly affect the GI tract and lead to weight loss. Fighting an infection anywhere in the body requires extra energy, and if dogs dont eat more, they will lose weight.

• Kidney and liver disease: When the kidneys or liver dont function properly, waste products of metabolism build up in the bloodstream, which can make a dog nauseated and not feel like eating. Dogs with kidney disease may also lose protein in their urine, which can lead to weight loss.

• Heart disease: Weight loss is common as heart disease progresses. The exact causes of this are unknown, but the condition goes by the name cardiac cachexia.

• Addisons disease:Dogs with Addisons disease (hypoadrenocorticism) dont produce enough of certain types of adrenal hormones, which can lead to poor appetite and weight loss.

• Hyperthyroidism: Although hyperthyroidism is rare in dogs, it can increase their metabolic rate and lead to weight loss.

• Neurologic conditions: Any disease that adversely affects a dogs ability to eat and swallow can result in weight loss.

Is My Dog Too Skinny?

Regularly checking your dogs weight by using an accurate digital scale is the best way to monitor for weight loss or gain. However, evaluating a dogs body condition score can also help you determine if your dog is too skinny. In general, a dog might be too skinny if:

• You can easily see their ribs or other bony points.

• When looking down from the top, they have a very pronounced waist.

• When looking from the side, they have an exaggerated abdominal tuck.

When to See Your Vet About Your Dogs Weight Loss

A little bit of weight loss isnt always an emergency. As long as your dog doesnt have any other signs of illness, you could try to change their diet or environment to see if it solves the problem. But there are times when you should get your dog to a veterinarian ASAP:

1. Puppies shouldnt lose weight! As they grow, puppies should be gaining weight, so call your veterinarian immediately if your puppy is losing weight or getting too skinny.

2. Weight loss in a dog thats older or has an underlying health problem is always concerning. The risk of serious diseases that cause weight loss increases as dogs get older.

3. Weight loss combined with symptoms of illness is never normal. Make an appointment with your veterinarian if your dog has difficulty breathing, vomiting, diarrhea, coughing, sneezing, weakness, lethargy, increased thirst and urination, or any other worrisome symptoms. If your dogs symptoms are severe, call a vet immediately to determine if you should head to the clinic right away.

4. Rapid or pronounced weight loss should always get your attention. Any health problem can lead to serious weight loss. Make an appointment with your veterinarian if your dog has lost more than 10% of their normal body weight or is losing 2% or more of their body weight per week. Heres what that can look like for dogs of different sizes:

Serious Weight Loss in Dogs

How Do Vets Treat Unexplained Weight Loss in Dogs?

A veterinarian will start by asking you a lot of questions about your dogs diet, appetite, environment, behavior, medical history, and any current medications (including parasite preventives) or supplements that you are giving. They will also determine how many calories your dog is taking in each day and if this amount should be meeting their energy needs.

Next, they will perform a complete physical examination and use the information they uncover to recommend treatment or further diagnostic testing. A basic laboratory workup includes a fecal examination, bloodwork, and a urinalysis. Additional testing can involve x-rays, ultrasound examinations, specialized lab tests for specific health problems, endoscopy, exploratory surgery, and tissue biopsies.

Whenever possible, veterinarians will recommend treatment for a dogs weight loss that aims to cure or at least improve its underlying cause. For example, they will prescribe a dewormer if a dog has intestinal parasites, dental care for damaged teeth, or antibiotics for a bacterial infection. Oftentimes, a change in diet can also help dogs regain the weight theyve lost. Options include:

• High-calorie, nutrient-dense dog foods for generalized weight gain

• Highly digestible diets when GI function is impaired

• Dog foods with added fiber may be appropriate for some types of GI problems or for dogs with diabetes

• Hypoallergenic dog foods made from novel ingredients, hydrolyzed proteins, or individual amino acids for food allergies and intolerances

• Disease-specific diets like those designed to help manage kidney or liver disease

The right food and other treatments will depend on the specifics of your dogs case. Dont wait too long to get your dog the care they need. Its easier to manage a dogs weight loss when it hasnt had a chance to progress too far.
