Are you aware of STD carried by dogs? I know few among birds and Game fowls like the Virus called Mareks that can be transferred by hens for life. So, I decided to start a study and look for a system where in I can put all the the procedures and health prevention that breeders can do? I think, In this way, we can educate readers and pet lovers. Any suggestions?

Fortunately we do not have Canine Brucellosis,  a notifiable disease,  in the UK.

When I travelled to the USA the dog was tested.

Fortunately with studs in my breed having very little stud work in their lives (a dog siring more than 10 litters in his life would be unusual) outside Scandinavia, such ussues are unlikely, with long intervals between matings.

Bitches rarely have more than two or three litters

Canine Brucellosis was indeed well known in N.America and for that reason many popular stud dogs, in America especially, never mate their bitches naturally.   They use AI.    Even here, most knowledgable breeders would make sure they clean their stud dogs after being mated - some even ask for the bitch to be on a broad spectrum antibiotic, much as when I was asked to do this once, and asked my vet to prescribe some, she said 'what for?   Your bitch isn't infected!!'    She was didn't and she was right.   I my opinion.

I heard of Artificial insemination before and vets often recommend this for pigs and other big animals. About antibiotics, I think you are referring to the "flushing method" where in you give them antibiotics to destroy and prevent bacteria from growing and we do this for game fowls as well.

Actually, it was my first time to read bout Canine Brucellosis, I am going to read more about this.

I don't think that vets actually recommend AI for large animals, it's just that it is not practical for many small farms to have male animals on their premises that are suitable for all their females. For example, I have a Dexter bull with my Dexter cows, but am considering AI for my 2 South Devon cows and for my bull's daughters.

Yep - pretty much.   It's to avoid the risk of infection but again my then vet said she didn't like prescribing antibiotics as a belt and braces treatment.   I suppose if the stud dog is popular, there is an increase risk of picking up some infection - which is why I'd prefer not to use a popular stud dog, or at least not one who had a bitch shortly before mine!!   And I always cleaned my dog after he'd had a mating, not that I let him be used very often, turning away more enquiries I had, than I accepted because I knew the bitch put to him, wouldn't nick.   And bearing in mind the male is often 'blamed' for things that go wrong
