My Mia is 10.5 months old and still hasn't had her first heat; Is there an age they reach when I should start to worry? I am going to have her spayed but wanted to wait until after her first heat. I was told that if you do it before there first heat the dog is less likly to mature as fast or completely. She is EXTREMELY hyper so I figured i would wait and see what happens. What age did you babies go in there first heat?

Welcome to the site.  We hope you can post some pics of  your girl.  MOST female dogs come into first heat around 6 mos. of age.  Every one of my female dachshunds did.  I've heard of some coming in sooner and some later (but I don't know how much later, sorry).  Has your vet commented on this delay in Mia's first heat being unusually late?  My current vet  doesn't like to wait for the first heat cycle and discusses neutering puppies almost on the first visit to her office.  She thinks it's stoo hard on the dog if you don't plan to breed anyway.  She likes to spay as soon as sex organs appear fully developed (5-5½ mo).   I had no intention of breeding my girls so both were spayed at 5½ mos.

I am taking her in tomorrow to see what they say, If she isn't in the beginning stages of heat, Im going to schedule her to get fixed. How painful is it? How do they act once its over? My vet keeps them overnight the first night.

I am not sure I get what you are saying?  What do you mean getting worse. Do they bleed?  Why would they cauterize her nails?  Jack has SLO whis is an autoimmune nail problem, but I am not sure what you mean by "mostly pink".

Do you mean the quick is too long?  I've never heard of this.  I suppose it would be done while she was still drugged from her spay. 

I had my girls spayed at 6 months.  My vet keeps females overnight too after spaying, and sent them home with pain pills, just in case.  They were slower and sleepy the next day, but by the second day home they were their normal selves, if a little slower.  I did give them one or two pain pills when I felt they needed it, but other than that, they were fine.

Yes, the quick is to long. Ever since she was a baby they have been long but now almost her complete nail is quick. The vet recommened me have he cartarized while she was under. I had never heard of this before but if i cant trim her nails without making them bleed I think It should be a option.
