With no home pregnancy test available for pets, it might be difficult for you to find if your dog is pregnant or not. Therefore, to help you find it out, here are some canine pregnancy symptoms that you can check.

Behavioral changes:
Any change that you notice in your pet’s behavior may be an indication of pregnancy. For example, an affectionate pet may seek to be left alone or a stand-offish may become clingy.

Changes in appetite:
During the first few weeks, a drop in the appetite may be noticed as your pet may become reluctant to eat anything. However, the appetite returns with gusto to support the pups and will require twice the normal amount of food.

Vomiting:
Your pet may vomit intermittently during the first few weeks of pregnancy at any time of the day. However, this symptom may not occur in all.

Breast development:
Though many of the female dogs will show some level of breast development after a heat cycle, continued growth can be a good indicator of pregnancy.

Methods of diagnosis

Abdominal Palpation
The individual sacs can be palpated at approximately 28 days post LH peak in the dog. However, the individual sacs can no longer be differentiated as the uterus gets larger.

Radiography
Fetal mineralization can be seen radiographically at approximately 45 days post LH peak in your pet. However, masking by overlying viscera with ingesta, scant fetal mineralization and underexposure may be the reasons for missing a diagnosis of pregnancy radiographically.

Ultrasound
This is an excellent way to determine pregnancy in your dog. Canine pregnancy ultrasound is the best way to determine if the fetuses are viable and what the gestational age is. Due to the safe and accurate diagnosis it provides, most of the experienced veterinarians prefer ultrasound to diagnose pregnancy or any other issue in your pet.
