Don't be alarmed unless it is prolonged. If it lasts more than a few days,  consult a veterinarian.

The best indication of a dog's general well-being is its weight and coat  condition. Several factors need to be considered in deciding the best weight  for any individual Greyhound.

A highly conditioned dog will have more muscle mass, which is both denser and  heavier, than the same size dog that is out of condition. Age, exercise,  stress caused by both heat and cold, and general healthy all influence the  best weight for an individual dog. Consult a qualified veterinarian,  preferably one familiar with sighthounds, about the ideal weight of a  Greyhound and try to maintain it.

A few additional tips for managing a Greyhound's weight include:

1. Many dogs respond better to portion-controlled feeding twice a day. Smaller meals fed more frequently are generally recommended for large chested dogs that may be susceptible to bloat.
2. Dog treats add calories. If trying to put weight on a dog, fine; but be careful the treats do not become a substitute for regular feeding. Include treats in the calory count along with all other food.
3. Vitamin supplements may not be necessary, but they will not likely harm a dog either. The best policy is to consult a qualified  veterinarian.
4. Total caloric intake to maintain a good weight for a Greyhound  will be influenced by the dog's age, the amount of regular exercise,  in some areas, the time of year.
5. A dog recovering from an injury or severe illness will need more calories than an otherwise healthy dog.

Managing a dog's food and weight can be handled in different ways. For those  interested in keeping track of calories, be sure to include ALL the food and  treats given a dog, particularly the potentially high calorie "table  scraps."

The following chart shows the calories needed to maintain weight for dogs kept  as pets getting moderate exercise:

 50 lbs.     1,350 calories

 57            1,482

 66            1,650

 88            2,112

118           2,832


 

A healthy Greyhound at the correct weight, will not look emaciated, but will  still look sleek (and probably a tad thin to the untrained eye), said Sue  Riegel, The Michigan Greyhound Quarterly.

Look for the following in a Greyhound that is "just right:"

• A few vertebrae visible
• One or two ribs showing (just slightly)
• Hip bones showing (just slightly)

Bear in mind these are just guidelines, not hard and fast rules. Vertebrae and  ribs may disappear very quickly in some Greyhounds as they reach optimum  weight, but you should be able to see just a hind of the hip bones, Riegel  writes. If you can't see them at all, your dog is getting to be a little too  "Well fed." If you can't even feel them, your Greyhound is becoming obese.
