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.

The heat cycle of the female dog has three parts and lasts about 3 weeks. The first part lasts anywhere from 3-14 days during which a bloody discharge and swelling of the vaginal area are usually seen. Next the dog will become receptive to being bred and actively may seek out a male dog.
Although it varies with different breeds and individual dogs, an unspayed female usually goes into heat twice yearly, about every six months. How Long Does a Dog Stay in Heat? The time during which male dogs are attracted to a female dog is variable, approximately 18 days. However, females are receptive to males for only about half of this time. How Can I Tell if My Dog Is In Heat? During estrus, your female dog may appear nervous, easily distracted and more alert than usual.
