our neighbouring farm rang this  morning to ask what to do....their 16 year old collie had been mated by another farmers dog that had wandered in when it got wind of her. I said she must take her to vet immediately and get her jabbed. She rang me back later today to say the vet had told her to wait until her season was over and then get her jabed so is this the new way of doing it or did she misunderstand? Would hate to think of this poor old lady being in whelp

Hi Sam
I always thought sooner rather than later? but maybe they do things differently now...never had to do it luckily, but I know some who have and they do it ASAP.

PS the pics are lovely..thanks

Some of the newer treatments are more effective used later, and can be used up to 42 days in whelp.  It is the old treatment that is done within 48 hours of mating and basically restarts the season.  I think the new one works differently.  I believe it is the same or similar to Galastop which is used for phantoms.

I think it's 3rd and 5th day.

I expect that the vet may also have a worry that whilst the bitch is still in season the same thing could happen again, it would be the worst thing for her to have the jab, which may or may not stop her season and then the dog to get to her again.

Bless her, what a shock at 16.

If she were younger I would say just spay her, but teh hormones in the treatment hqave quite a high risk of setting off Pyometra.  Nearly everyone I know spays their bitches by middle age to avoid problems liek thsi in aged bitches.

The older way was to use measolin (sp) quite early on after an accidental mating, the outcome was not always guaranteed and could possibly lead to a pyo, the newer version can be used upto 42 days after mating and has fewer risks but is not risk free and doesn't guarantee the bitch carrying the pregnancy to term though, in perspective the failure rate of it is quite low.
