Basset Hound nutrition: weight, spine, bloat and ears

For a Basset Hound, body weight is the nutrition question that matters most, because extra kilograms sit on a long back and short, heavy legs. The American Kennel Club breed profile gives the breed as up to 15 inches (38 cm) tall and 40 to 65 pounds (18 to 29 kg), with a life expectancy of 12 to 13 years. That is a lot of dog on a low frame. The other diet-related concerns in the breed, bloat and ear disease, are covered below, but a lean Basset makes nearly every other problem easier to manage.

Why Bassets put on weight

Overweight Bassets are common enough that the heavy look has come to seem normal. When researchers scored the body condition of dogs photographed at Crufts, Basset Hounds were among the breeds most likely to be overweight, along with Pugs and Labrador Retrievers. If dogs at a major show carry extra weight, owners who compare their own dog with them may accept it too.

The breed's shape adds to the difficulty. A deep chest, loose skin and heavy bone make it hard to judge fat by eye. Hands are more reliable than eyes. Run flat palms along the ribs: in a Basset at a healthy weight they should be easy to feel under a thin layer, and from above there should still be some narrowing behind the ribcage. Many Bassets are also strongly food-motivated and not especially active, which is a simple recipe for slow gain.

The Merck Veterinary Manual gives a starting formula for calories. Resting energy requirement (RER) is 70 times body weight in kilograms raised to the power 0.75. An intact adult dog needs about 1.8 times RER, a neutered adult 1.6 times, and a dog that gains weight easily 1.4 times.

Figures are rounded to the nearest 5 kcal. For a neutered, easygoing Basset, the right-hand column is often the more realistic one. Work from the dog's lean weight, not its current weight, and recheck body condition every two to four weeks after any change. Feeding guides on bags are written for an average dog and tend to overshoot for a breed like this.

The spine and joints

The Basset's short legs come from chondrodysplasia, a form of disproportionate dwarfism. A 2009 genetics study linked it to an extra copy of the FGF4 gene that defines the short-legged look in at least 19 breeds, including the Dachshund, Corgi and Basset Hound. Selection for this long, low shape is linked with disc abnormalities, which is why intervertebral disc disease is a concern in these breeds.

In a disc extrusion, disc material pushes into the spinal canal and presses on the cord. The result can be anything from back pain to paralysis. A UK referral-hospital study measured dogs of many breeds and found that relatively longer backs and being overweight both increased the risk of thoracolumbar disc extrusion. Weight is the part an owner can change.

Bassets are not simply large Dachshunds. In a comparison of dogs seen at three neurology departments, Basset Hounds with thoracolumbar disc extrusion were older at presentation than Dachshunds, more often affected further back along the spine, and more often able to walk when discharged. The disease was still confirmed in over a third of the Bassets in that referral population.

Signs that need a vet the same day: a hunched back, crying when picked up, reluctance to climb or jump, wobbling or knuckling of the back feet, or any loss of use of the legs. Rapid treatment gives the best outcome.

Glucosamine, chondroitin and fish oil are widely sold for joints. None has been shown to prevent disc disease, and there is no established dose specific to Bassets. They can be discussed with the vet for a dog with arthritis. For prevention, the useful measures are practical: a lean body, ramps instead of jumping off furniture, walking gear that takes pressure off the neck for dogs that pull, and supporting both chest and hindquarters when lifting.

Bloat and meal routines

Gastric dilatation-volvulus (GDV) is a stomach that fills with gas and twists, cutting off its blood supply. It is mostly a disease of large, deep-chested dogs, but the Merck Veterinary Manual lists Basset Hounds among the breeds at risk, together with Great Danes, German Shepherds, setters, Weimaraners, Saint Bernards and Standard Poodles. Merck names once-daily feeding, feeding only dry kibble and eating fast among the factors associated with GDV, along with older age and a close relative that has had it.

• Feed at least two measured meals a day instead of one large one.
• Slow a fast eater with a slow-feed bowl or by scattering kibble on a mat.
• Allow a quiet period around meals rather than hard play straight after eating. This is common advice; the evidence behind it is weaker than for meal number and eating speed.

The signs of GDV are a swollen or tight belly, retching that brings nothing up, drooling, restlessness and collapse. A dog showing them needs a vet immediately, at any hour. The disease can progress to shock within hours.

Ears and the role of diet

Long, heavy ears may reduce airflow into the ear canal. In a large UK study of dogs under primary veterinary care, Basset Hounds had nearly six times the odds of otitis externa compared with crossbred dogs, and breeds with pendulous ears had higher odds than breeds with erect ears.

Most ear infections are managed with cleaning and treatment prescribed after the vet has looked in the canal and checked a sample for yeast or bacteria. Diet comes in when infections keep coming back. Allergic skin disease, including food allergy, is a common underlying cause of recurrent otitis, and a vet may suggest an elimination trial: a hydrolyzed diet or a protein the dog has not eaten before, fed strictly with nothing else for several weeks, followed by reintroducing the old food to confirm the cause. Swapping between ordinary commercial foods does not test for food allergy, because many share the same proteins.

Head shaking, scratching at the ears, redness, odor or discharge warrant a vet visit. Chronic, untreated otitis can thicken and narrow the canal permanently.

Choosing and portioning food

• Food type: a complete adult food, often a weight-management formula for a dog that gains easily. Lower-calorie foods let a Basset eat a satisfying volume for fewer calories. Check the calorie content per cup or per 100 g on the label, because "light" means different things across brands.
• Protein and fiber: when a dog is losing weight, adequate protein helps preserve muscle, and fiber adds bulk. A vet-prescribed weight-loss diet is the safest route for a dog that is clearly obese.
• Measuring: weigh dry food on a kitchen scale. Cups and scoops vary with how they are filled.
• Treats: count them in the day's calories and keep them small. Pieces of green bean or carrot make low-calorie rewards.
• Weighing the dog: weigh monthly. A Basset is heavy to lift, so the clinic scale is usually easier and safer for the back.
• Puppies: feed a complete puppy food in measured meals and keep the puppy lean. Extra weight on a growing chondrodystrophic skeleton brings no benefit.
