Pregnant fur mommy

Is it possible ba na nasesense ng dog pag buntis ka? It seems like my dog started to hate me nung nabuntis ako. Lumayo loob niya sakin at ayaw na lumapit. I tried to take a pic of her with my ultrasound pero tumakbo palayo and hide from me, and barely eat after that day. 😢 Nag woworry ako na kung ngayon palang ayaw niya na sa baby ko, what if pag lumabas na si baby, di niya kaya kami pahirapan? P.s. my dog was our only baby for 2 years, at tinuring talaga naming baby.
