Update on the condo that won’t accept my 40 pound labradoodle (MA)

[I wrote a post about trying to buy a condo from a friend which is really just half of a house.] The HOA is two people. (https://www.reddit.com/r/RealEstate/comments/1siubkm/buying_a_condo_that_is_a_converted_house_with_one/) They had a problem with my dog being over 35 pounds, but all communication was done through my friend and they made me promise not to contact the other owner directly, which is a red flag. The update is, I insisted on speaking to the other owner, and I was told they refuse to talk to me at all until the sale is finalized.

Is this a normal way for a co-owner in this situation to behave? It seems like a huge problem to me. I told my lawyer I'm withdrawing from the property. I have never bought any property before and this is my first attempt trying to get a condo. I decided to give up on this idea and get an apartment until I learn more about how condos are supposed to work.

PS I got a lot of comments on my thread about my dog being an ESA. These comments all seem to believe an ESA is just a fake service animal and has no legal protections. This is false, ESAs do not have the same rights as service dogs and but they do have legal protections. In the state of Massachusetts they are both classified as "assistance animals." I got an ESA letter years ago from my therapist who I have seen in person for years, my dog is highly trained and was trained specifically as at therapy dog. My friend was pushing me to legally force my dog onto the property, which is possible but I do not want to deal with that conflict. So I do not need any advice regarding the ESA issue but I just thought it was annoying that every comment I got on the matter was both judgmental and incorrect.
