A pound of fat contains roughly 3,500 calories, so a 500-calorie-a-day deficit will cause you to lose about 1 pound each week. You can achieve this by eating 250 fewer calories than usual -- provided your weight is steady on your current diet -- while burning about 250 extra calories per day with cardio.
How Long Does a Dog Stay In Heat? Dogs are usually in heat for 21 days. Female dogs have a cyclic sexuality that is independent of season unlike most animals. As for the male dogs, they do not have any cycles and are always ready for intimacy like most males of any species including human beings.
The dog will then continue to go into heat approximately every 6 months or twice per year. Most female dogs are in heat for 18 days, although male dogs are only interested in the female dog for about half of this time. It is recommended that if the owner does not intend to breed the dog, then she should be spayed either before or after her first heat cycle.
