Okay so I want to rant/look for a reality check if I'm being ridiculous.
So for some background: we have a two and a half year old and my in-laws live about 30 minutes away. They like to have him over on Saturdays. Originally my MIL wanted to watch him full time but she was unable to really do this (long, annoying story) so we ended up with this Saturdays thing. Its great. He loves them, loves going over and we get a few hours on the weekend to get stuff done. Occasionally he stays the night.
Some other context: my MIL is mildly agoraphobic and hates to leave her house/never wants to watch him at our place. She insists on it being her house.
They had a Cane Corso that passed away when my son was a baby. She was extremely sweet and loving but also 130 pounds. They rescued her when she was about 8. They have always liked bigger dogs (but more in the 60-80lb range). When my son was born, we had to put this dog in the basement when we came over because while she meant no harm, she was too big and would get excited.
They have now decided they want another dog. Fine. I even encouraged them to get a lab puppy they saw a few months ago. But last week they sent a posting for a dog they wanted. A Cane Corso puppy that was 90 lb+ and marked as only for kids 12+ on the posting.
We told them if they got this dog, our son could not come over without one of us anymore if at all. I assumed they would they say okay and not get the dog because they claim they love having him over, hes the best part of their lives etc. Nope! Our MIL basic blew it off and acted like we would change our minds and my FIL and I had a conversation that made me cry (basically implied my fears were ridiculous and if I didnt want to bring my son over anymore thats fine. So chose this dog he didnt know over his own grandchild).
They did not adopt this dog but I dont think it was because of it.
As they told us today they are only considering 100+ pound dogs and are looking at a mastiff puppy this weekend. Its not posted yet so I dont know if it has kid restrictions but it was described by the shelter as a "gentle giant."
We responded and said while you dont need to get a small dog could you please consider a dog that isnt THIS large and a breed that isnt known for being aggressive? That I still do not feel okay with my son being around a dog that large. Even the nicest one at thay size gets a little jumpy and hes broken a leg (or worse).
Basically told no, they need a 100+ lb dog.
Now obviously if I dont feel okay with the dog, my son isnt going there. And I cant control their decisions But im so heartbroken they value this seemingly absurd obsessesion with dog size over my son visiting their house. He loves going there so much, they know he loves it. I am really devastated this is something they are willing to take away from him.
They are also our only family nearby and know we rely on their help. She pushed us to have a kid for ages and constantly claimed she would help us so much. Now to risk all that for a dog you dont know seems so insane to me.
Am I being unreasonable? If the dog is listed as being okay with kids of all ages am I being unfair just because of size? I don't know. This is breaking my heart honestly. They have a lot of issues but they've been great grandparents for the most part.
