My female chihuahua

Question
HI i have a ? ok my female went into heat last year in November on the 5th.how long will it be before she goes back into heat?and Can a chihuahua go into heat without bleeding cause she smells bad

Answer
Hi Elizabeth. Most dogs usually go into heat every 6 months or so. Any dog can actually have a heat cycle where they don't seem to bleed. It's called a dry, or silent heat. She shouldn't be smelling bad. I'd take her in for a check up, she may have an infection. Good luck!
