I bred my chihuahua 1 week ago now she is being quite aggressive, is she pregnant?

Answers:
you won't know yet. she is going out of breeding period and doesn't want the male messing with her . it will probably last for another week.

she's provable pissed of at you because
of all the discomforts of pregnancies.

Usually the first signs of pregnacy are personality changes. It's her hormones! There is a good chance she is pregers.

---

highly likely!. it's common to notice a change in the behaviour of dogs when they get pregnant, due to hormones. just like people ;op

---

She's probably in discomfort, you shouldn't have bred her with that Great Dane!!

---

Shes probably recovering from losing her virginity.its a bit step..give her time!!
