Are mini dachshunds dogs allowed?

I belief dogs are allowed. Double check on their website.

Yes

I think i saw some small digs

Dogs are only permitted in the parking areas, not in the gardens proper. We have brought our corgi, parked in a shady spot and left him in the car safely. All depends on the weather and temp.

Site Guidelines specify that only service animals are allowed. So, if your dachshund meets that requirement, you're good to go.

I would check website.

Did not see any dogs in our 4 hours there, but did not see signs saying no dogs either..

I did not see any digs there when we were there. Check their website.

There were no signs saying no dogs when I went in August
