I have a good friend that is evaluating the use of Cheque drops on a more long term basis. One of the primary concerns is that for every heat the female dog goes through, her uterus is more damaged, more susceptible to pyometra as she gets older (over 5) and less able to have a successful litter. Based on the literature it appears that Cheque drops over a long time period helps to protect the uterus.
The main items that are taken into consideration before making the decision are (1) the medication cannot be used before the bitch has had at least one normal heat b/c the drug speeds up the closure of the growth plates. (2) the liver and kidneys must be normal (3) the dog cannot have a progesterone dependent tumor present and (4) the bitch should have a normal personality. (not abnormally or pathologically aggressive) .
Although the abscence of heat cycles during the trial season is a side benefit, this is not the primary reason for looking at Cheque.
From a review of the literature it appears that this is a very safe drug (as safe as any drug) and has been in use for over 20 years. I realize that folks may have strong feelings about this, but Dr. Hutcheson himself uses it on his bitches for an extended period of time, with no apparent negative side effects. Of course there are always issues, but the benefits seem to far out weigh the risks.
Dr. Ed, I know you have used this as I did do a search, but I am curious if folks have used this drug for more than a couple of months and what experiences they are having.
Thanks in advance
