acts like she's sick! HELP!? My 8 month old aussie mix was acting weird yesterday morning, like she was sick. She was laying around, very lethargic, has no energy, she always looks uncomfortable too. I was really worried about it, so my boyfriend went outside with her and saw that she is in heat for the first time. We figured that that was why she is being so weird, but when I came online to find something that correlates the two, I have found 0 results! So I'm suuuper stressed out again, and would like to know if anyone, like a vet, or someone who's gone through it; is her behavior normal? Or should I take her to the vet?
Thank you so much
