Your dog's digestion rate isn't affected by his size as much as by other factors, including the type of food you give him, the amount of exercise he gets, the amount of water he drinks and more. For example, an average dog -- big or small -- takes between four and six hours to digest canned wet food.
Every woman's metabolism is different, but as a general rule of thumb, you should allow 1 day for every 1,000 units of hCG you injected. The standard hCG dose is 10,000 units; thus, 10 days after the shot, the synthetic hCG should be gone and you should be able to test for pregnancy without detecting the shot. However, you should ask your doctor what the recommended protocol for your dosage is..
After testing, you can confirm results by seeing your doctor, who can perform even more sensitive pregnancy tests. Blood tests are done at your doctor's office, but are used less often than urine tests. These tests can detect pregnancy earlier than a home pregnancy test, or about six to eight days after ovulation. But with these tests, it takes longer to get the results than with a home pregnancy test. Two types of blood pregnancy tests are available: A qualitative hCG test simply checks to see if hCG is present. Doctors often order these tests to confirm pregnancy as early as 10 days after a missed period. However, some of these tests can detect hCG much earlier. A quantitative hCG test (beta hCG) measures the exact amount of hCG in your blood.
