Ok, my pup is 1.5 years old, and she has had her first heat at the 8 month mark. 

This heat was extremely long, lasted for 7 weeks.  By the end of the heat, she was so lithargic, that she couldnt raise her head for a cookie.  I took her to the vet, and she said nothing was wrong (no infection)

She was due to come in again last month, and didnt.  Had all the signs she would, but I noticed last time before she came in she was rather swollen for about 2 weeks before any bleeding occured.

She is wetting more.  I mean, normally she goes outside 4 times a day, to use the washroom.  Yesterday, she had an accident on my bed, then an hour later, in her crate.  She also had 2 accidents overnight.

Is this a sign she is coming in?  Or could it be something else?  None of my previous bitches have done this, wetting constantly, so I cant really judge based on them.  Also, this bitch didnt wet last heat, but I have read on here that heat cycles change each time.  I am concerned that this could be something more, although she doesnt have any discharge and her urine is of normal colour and smell. 

Any advice would be great.  BTW I did search and all the topics I could find any info about were how long between heats and stuff like that. 

Thanks!!!!!!

never heard of a season lasting that long! and a lethargic dog but nothing wrong with it?? i would change vets pronto

I would insist on getting her checked out for pyro or some other womb/overy problem. if they won't examine her, change vets or at least get a second opinion.

Prolonged seasons can also be a sign of cystic ovaries (which can also be painful) and of course be a reason for infertility.

I never heard of a bitch being in season for 7 weeks either.  One of mine always has slightly prolongued.  Total till the end of her season the complete end of bleeding was just over 4 weeks and never ovulated until well after 20 days.  She also always has somewhat heavy bleeding during her seasons as does her mother and her grandmother but all produce somewhat large litters for the breed.  7 weeks to me sounds a little suspect and I would certainly be asking for a second opinion.

I am gonna call another vet anyways, as I am a little annoyed with the vet I have now, for a multitude of reasons. 

I hope she doesnt have an infection or anything, and just that she is really late. 

Apart from her wetting, she appears fine.  I took her temp last night, and she was within normal range (38 C), so when I called the vet back they said that she could just be really late, and possibly mad at me for something, that dogs spite their owners when things change in the house. 

I found a vet, when calling around about tails and declaw removal, that is what we call a "breeders vet".  Pretty much everyone that works their breeds something (be it cats or dogs) and makes sure they are health tested, shown, etc.  So I am going to call them when they open, and see if I cant make a consultation for my little girl.

I will let you all know what they say

Would get her to another vets to get a full health check. Seasons do not last that long unless something is pyschically wrong with the dog. I would ask for a full blood work on your girl and also take a urine sample with you to check she hasn't got a water infection. Bitches do wee more when they are coming into season but this is just usually a marking habit with very little urine passed. Good luck and hope everything is ok
