I guess I wanna know if I’m the AH here but I also need advice. There is important context/background information so please read. I also wanna state that despite all this, I still absolutely adore my boyfriend and his family but this is something that has been nagging at me.

So basically my boyfriend’s mum is disabled. She has severe arthritis and she’s had it for about 20 years (since she gave birth to my boyfriend, we’re both 20). During this time she gained weight. A lot. Which I get, it’s hard to keep weight off when you’re in pain when you move. But she doesn’t go outside, like at all. If she does, it’s in the car and it’ll only be to the shops or to her daughter’s house. She is lovely but I’ve noticed since I’ve been with my boyfriend (4 years) that she doesn’t have a lot of common sense and neither does my boyfriend which has caused issues for us in the past. His mum tends to go with her heart and not her head which often leads to poor decision making.

My boyfriend’s brother has very bad mental health: depression, anxiety, bipolar, suicidal the whole shabang. He’s been on medication for a long time but is still waiting to be seen by a proper therapist to give him a higher dosage of medication. Anyway, recently they think he has fibromyalgia which is basically when you’re in a lot of pain and you’re tired and all that. Idk if it is fibromyalgia or if it’s from his depression bc I know depression can cause physical discomfort. Point is, he doesn’t leave the house much either, he’s basically disabled.

My boyfriend works full time 10 hours a day all week. He is very tired when he gets in from work which I don’t blame him. However, I know that my boyfriend is also a very lazy person (for like the first two years of our relationship he didn’t really do anything and just slept and played video games. He’s not an active outdoorsy person whereas I am).

My boyfriend’s sister has her own house which she lives in with her boyfriend. She has two children, 9 and 7 I think, from a previous relationship and a one year old with her current boyfriend. She had a false pregnancy before she had her last baby and when my boyfriend told me about it I explained that I was sorry for her but that perhaps it wasn’t the best time for a baby. She didn’t have a driver’s licence, her boyfriend works 6 days a week to pay for the house they moved into about 2 years ago, she works in a cafe full time and my boyfriend has pointed out that she doesn’t give her children the time and attention they need. So I gently suggested to him in private that perhaps it was a sign that now wasn’t a good time for her. He got defensive saying that she should have a baby now otherwise there will be too much of an age gap between the baby and her two other kids and that they won’t bond as well otherwise. I explained that an age gap has nothing to do with it (having a big age gap between me and my siblings) and that it is down to who they are as a person and how they are raised together. Anyway, she got pregnant and had a baby and now she asks my boyfriend’s mum to babysit it almost everyday because she has to work all the time.

Now onto the problem. My boyfriend and his family lost their two dogs last year. They were German shepherds, one was 9 and one was 11. This is kinda old for them as they were very big. They never really walked them during my time with my boyfriend but I just put it down to their age and that they didn’t want to exercise them too much. Anyway, since his family lost them, his mum was looking at other dogs. She was looking at puppies and I told my boyfriend in private that I didn’t think this was the best idea since puppies need lots of training and exercise and with two of them disabled and him working full time, I don’t see that happening. I suggested that they get an older rescue, not necessarily one on it’s last legs but one that won’t need as much exercise so it can fit in with their lifestyle. My boyfriend and his mum said they would think about it. Anyway, about 3 weeks ago, my boyfriend’s mum says that she’s found two German shepherds that are brothers and they are one year old. She picked them up and they are currently fostering them. My boyfriend told me how energetic they are but they are also quite reactive and food aggressive (I also have a rescue that is very reactive and extremely good aggressive, it’s taken us 3 years to get him to trust us and his is still reactive and this is just with one dog and we also have experience with rescues, my boyfriend does not). My boyfriend’s house is also quite small with lots of things around so not much space for two young full grown German shepherds to play. I asked him how are they going to walk them and he said his brother will walk them in the morning and then he will walk them in the evening. He quickly realised that they are too strong and reactive for one person to walk them on their own so they only get one walk a day now and that’s if my boyfriend isn’t tired after work which he always is (understandably). I asked my boyfriend last night (Thursday) when they were last walked and he said Monday. I said that they need to be walked everyday especially if they are only being walked once a day since they are so young, they need the mental stimulation and the exercise. He explained that they give them chews and play with them and let them out in the garden. I told him it’s not the same and that young dogs need to be walked. I have also given him suggestions when training them such as getting crates for them so they have a safe space for them to go in when they are anxious or if they need separating or if they are naughty (we have a crate for our rescue and have put a blanket over the top so it is dark, this is his space and we only go into his crate if we really have to). My boyfriend said they can’t do that because their house isn’t big enough so I suggested that since they haven’t bought the dogs yet, that they get just one dog so they can fit something like this in and give it the proper training. I also suggested that he tells the dogs to leave their food when he gives it to them and only lets them eat it once they listen to him and leave it, since they are food aggressive this would help. My boyfriend hasn’t done this and idk why. My boyfriend’s mum is out babysitting for her daughter pretty much everyday like I said so she has to leave the dogs home alone.

I love my boyfriend and his family and I know they would never intentionally be cruel to animals but I know that these dogs won’t get the stimulation they need, they just don’t fit in with their lifestyle. Besides, two young German shepherds won’t be hard to rehome, but an older dog would be. But that is what they are suited for. This is why I said I don’t feel they think logically because they want these dogs but don’t seem to realise that they aren’t the best family for them. I’m not saying the dogs would be unhappy but I think they could be happier in a home that can provide regular exercise for them. I don’t know what to do because I’ve told my boyfriend all this and he won’t listen because he’s already in love with the dogs but I don’t want the dogs to miss out on proper exercise. What should I do?

Tl;dr: my boyfriend got two young German shepherds but he works full time and his mum and brother are disabled so these dogs aren’t getting the exercise they need. I’ve told my boyfriend he should reconsider getting these dogs but he’s already in love with them and won’t listen to me. What should I do?
