Please go read the science on Autism and Vaccines.

Is it as simple as an eye test, or would you request vaccine records for the dog which should also identify the breed of the dog?

Gone til the vaccine is here. 

My insurance gives me an easy way out of renting to people with these breeds.If you do allow them: make sure you have a vet certify the age, breed, and current vaccinations.

Doctor never billed my mom again once my dad died for normal visits, vaccinations.  

I wouldn't touch it with a vaccinated iron crowbar.

I feel confident that the market will return once a vaccine or another effective treatment is available, but concern that the near term events could push prices and rent down.With the recent price appreciation in markets due to less inventory and the current economic environment. 

Though I still have most of them as 3 are being sent to the UK and the pups need to be a bit older and have gotten rabies vaccination which you cannot do until they turn 12 weeks.

Thanks @Eric Schultz and after considering the stimulus passage, where we're at with vaccines and such, I agree with there being more appreciation juice left in the market.

Hopefully we will have a vaccine next year which will allow more people to go back to work.
