Roughly every six months.
Every 6 months
For female animals, they go in heat about every 6 months.
most female goes go into heat every 7-8 months
Dogs usually go into heat twice a year, although some individual dogs will go into heat more or less often. Typically, a female will remain in heat for about three weeks, although she will only bleed for the week to a week and a half.
Most pets lead sufficently artificial lives that they will go into heat according to their own rhythm and regardless of seasons. Hence chihuahuas can have puppies at any time of year.
Yes, a female no longer goes into heat if they are pregnant.
I breed chihuahuas for a living. It can happen at anytime but usually after they are a year old
I was told by my vet that they don't usually go into heat, it depends if you have a female on her own. I have a female Russian dwarf and she lives on her own and the vet said she wont go into heat.

every 6 to 12 months unless fixed if fixed no more heat and maybe depending on breed age may diminish it
Female dogs go into heat usually once a year. Sometimes they can go twice, in the fall and spring.
Every female hamster goes into heat. She often sets off a foul odor - sort of a way to let any male hamsters around her know that shes 'in heat and ready to mate'. P
Female cats should not go in heat when they're pregnant because it may harm the fetus.
