Pregnancy of dogs by the day: signs and symptoms
How to determine the pregnancy in a dog? Signs of pregnancy depend on the period. So until the third week, almost no changes are noticeable, except, perhaps, drowsiness and apathy.
- By the 25-30 day in the area of the mammary glands the skin swells and the glands themselves become clearly visible or pink in dogs with fair skin. In the area behind the ribs, the abdominal enlargement may be noticeable.
- Using ultrasound, pregnancy is diagnosed from the 21st to the 24th day. It is already possible on the screen of an ultrasound device to see amniotic bladders with embryos.
- Obvious signs of pregnancy are afterThe 29th day. Mammary glands increase greatly, and for 7-10 days before childbirth the experienced mothers have milk. Only a dog with the first pregnancy can produce milk during childbirth or a few hours before them.
- From the 33rd day the weight of the future mother begins to increase sharply.
- At the 6-7th week of pregnancy (between 38-45 days)In the uterus, individual fetuses are probed, the ribs and bones of the skull of embryos differ. During this period, using the X-ray, you can accurately determine the number of puppies. This is especially important with a large litter.
The first pregnancy
This is an especially difficult test for a young dog. The first pregnancy lasts longer than the subsequent ones, and it is more difficult to proceed.
The owner of a young bitch should not hope for"Nature", since domesticated animals are no longer the same as natural conditions. And in the forest, not all survive, but only the most healthy and strong.
Therefore, it is necessary to plan the first pregnancy for three to four months.
During this time the animal should have well developed muscles, excess fat is folded, the ration carefully selected, all vaccinations are made and fleas and worms are destroyed in time.
After the first delivery the dog can behaveToo restless: jump up, run around the room or aviary, as if "do not know" what to do with the puppies. The owner should not worry, after 7-10 days it will pass. You need to put the dog to the puppies and make sure that it does not accidentally injure the kids.
Anxiety of the dog that gave birth for the first time is often due to the fact that she has a lot of milk, and too little puppies can not suck it all out. When they get stronger the dog will calm down.

Experiencedkynologists also notice excessiveThe agony of a bitch. She seems to be going crazy. With special enthusiasm he builds himself a "nest", with particular care takes care of pseudo-puppies: soft toys, etc.
On the street, she is reluctant, and on return immediately rushes to take care of her "puppies".
With such manifestations of maternityContact the veterinarian. However, the host can accelerate the termination of the imaginary pregnancy.

Interruption of pregnancy in a dog
As for the consequences of an unplanned matingAnd the possibility of abortion, the veterinarians in this matter are divided into two camps. Some believe that it is better to get rid of unnecessary puppies, others that for a bitch a more healthy process is childbirth, not abortion.
