A few questions about Parvo

I vaccinate in the early morning or in the evening, from my experience I havent had any problems from the shot. I lost a whole litter about 2 months ago at first I thought it was parvo but the more I looked at it the more I think it was corona but my vet is an idiot and tells me that I dont know what im talking about and that there isnt much corona in this area... I have heard from friend that they have been having problems with it too..

How do you think Parvo got on your yard?

Bought a bulldog pup at Canton Trade Days, make sure that if you buy a pup from there it never touches the ground while there.

How were the dogs kept? ( on chains, in kennels, concrete floor, dirt floor, etc. )

This pup was in the house and taken outside to go to the bathroom

Where the dogs/pups that got Parvo first up to date on shots?

she was only 6 weeks old but she had her first shot

If any other dogs got Parvo, were they also up to date on shots?

Got lucky and she was the only one that got it.

Whats the oldest dog you've had to get Parvo?

3 months old

Have you had any new litters or new dogs come on the yard afterwards that got Parvo?

No but have had one litter get coronas a few months later and havent had any problems since (knock on wood)
