Dog Got Pregnant At Training Facility

Hi, I have a Great Dane that just turned one. I’ve been recommended not to spay her until she was 1.5 to 2 years old because it could affect her bone development. When my husband and I got married, we sent her to a board and train. They seemed very professional and the training was successful. But she’s been back for 2.5 weeks and we just found out she’s pregnant.

I’m looking into termination options but I’d like for the training facility to pay for it. They knew she was not spayed and guaranteed she would always be supervised and not around in tact males. I’m sure it was an accident, she did get kennel cough while she was there and they paid for her treatment & treated her promptly. I get the vibe from them they’d be willing to work with us but I would like some legal insights before I approach them and would like to handle this as simply as possible.

I really liked the trainers and company, and I really trusted them. I am uncomfortable with what happened, especially when they guaranteed her not being spayed will not be an issue and she’d be safe. Obviously if they paid it would help financially, but also possibly give them incentive to be more careful about these things.

How would you approach this? Is this an unreasonable expectation on our part? Thanks.
