1. Nesting Behaviour: A pregnant pit bull might start arranging or shredding towels, blankets, or other soft materials to prepare a comfortable birthing nest. This behaviour usually occurs a few days to a couple of weeks before labour.
2. Change in Body Shape: As the due date approaches, your pit bull's belly will become significantly more rounded and full as the puppies grow larger.
3. Decreased Activity: Pregnant pit bulls often experience fatigue and lower levels of energy towards the end of their gestation period. You might notice your dog resting more and playing less as birth gets closer.
4. Mammary Gland Changes: The mammary glands of the mother dog will usually swell visibly and turn pinkish in colour in preparation for milk production. You might also notice a discharge of clear or straw-coloured fluid from the nipples.
5. Loss of Appetite or Picky Eating: Some pregnant pit bulls experience a temporary loss of appetite or change in food preferences before labour. However, some dogs might keep eating normally.
6. Panting, Restlessness, and Vocalization: As labour approaches, your pit bull might start panting heavily, showing restlessness, and making low vocalizations indicating her discomfort and anticipation of labour.
7. Seeking Solitude: Some pit bulls prefer to find a quiet, secluded spot as they start the birthing process.
Remember, each dog is different, and these signs can vary. If you are unsure about your pit bull's readiness to give birth, it's essential to consult your veterinarian for guidance and care.
