Nobody is sure why dogs sleep so much. The amount of sleep that an animal needs depends upon its species. Horses and cows may sleep only three or four hours daily, because they require long hours of grazing to supply their bodies with sufficient food. Bats and opossums may sleep closer to 20 hours. The various breeds of dogs also seem to have different sleep requirements. Some very large breeds of dogs, like Newfoundlands, Saint Bernards, and mastiffs, often spend a great deal of their lives sleeping â perhaps up to sixteen or even eighteen hours a day.
When it comes to eating before exercise, it's all about timing. No matter what time of day you choose to exercise, make sure to plan your workout two to three hours after your meal. Going overboard with too much food right before a workout will leave you feeling sluggish and can lead to stomach discomfort.
Factors to Consider When Eating Before a Walk. The timing and size of your meals before a walking workout makes a difference. If youâre consuming a large meal, wait for about three to four hours before walking. If you consume a small meal, wait between two and three hours before you set off. However, after a small snack, you should be able to go walking within less than an hour. Keep in mind that these ranges are general and can vary from person to person. Your best option is to try various time periods to see which one works best for you. Possible Effects of Eating Before a Walk
