Possibly she is in heat and wants to mate.If she's pregnant , she's going in to labor. If she's not pregnant, check her over gently for wounds or a piece of glass in her paw, something like that. Be very gentle and be careful she doesn't bite you . Some dogs get aggresive when sick or in pain.If you find nothing, call the Vet. It may be something internal.And don't wait til morning.
If panting is for long time see your vet. She could be having complications.
The girl puppies will start acting strange then the boy dogys will start to follow them  and the girl dogs whine and the boy dogs grunt so that's how u know
my male whines when my female is in heat or they will both whine if they want to go outside. If yours is constantly whining it may be in pain
If your female dog is walking around panting and not sleeping, she may be in labor of she is pregnant. Otherwise, your dog may have a fever or be too hot for some other reason. Make sure your dog has access to clean water and call the vet if the behavior continues.
either you have a strange cat or its in heat
this is because it is finding somewhere to roost and it will probably want somewhere quite
Has he ever been outside alone before at night? If it has probably has been socializing with female cats. That is why he has been acting like that. The reason why it has been acting like that in that situation is because it has had some problems with that female and wants to be left alone. Or he wants to be left alone because of the way that female makes him feel. If not there are multiple reasons why it could be acting so strange. 1. it could want some alone time. or it thinks its a human and wants alone time at night. Sorry if he is a girl i don't have time to confirm if its a male or a female.
If there is another female around she can get domanate of her surroundings. A female pit in heat can be aggressive and even more so if she has has a litter recently.
a female octopus is called a hen, strange i know but true
Pretty strange question. 50% male 50% female possibly?
You are a sad, strange, little man, and you have my pity.
