Also posted in the doghouse, but wanted perhaps wider opinions.
DH and I have decided to get a puppy. He is joining our household in three weeks, and while everyone else has been really excited for us, my MIL and FIL especially have said some real negative things. They think that:
a) we can't take care of a puppy or dog because we both work full-time.
We do both work, but my job is very flexible location-wise and I work at home 2 days a week at minimum. I'll work at home until the puppy gets its jabs and then I will bring him to daycare on days I'm in the office. We also have family that could pop in for emergencies. I don't think that this is cruel or unreasonable. It's no different than if you had a child and worked full-time.
b) We can never go anywhere and it's like having a child without any of the benefits.
Surely this is ridiculous. One of the reasons I want a dog is because I spend a lot of time home alone and get really lonely. DH works long hours (as do I, but with plenty of breaks) and I suffer from anxiety/depression. I would like a companion to take out and love and fuss over. I spoke to my psychologist and they have said it could be really good for me. I don't want children, and I think maybe they are upset because of that? I'm sure they would not have responded that way if I'd said that I was pregnant.. 
c) What are you going to do when you want to go on holiday?
THEY HAVE CATS AND USE CATTERIES FFS. This really annoyed me.
Just need to vent about all this! I know having a puppy is a pain in the ass (trained my mum's when I lived at home), but they are just so negative and depressing. They are like that all the time which is why maybe it bothers me so much. I am worried about properly caring for my new pet and I'm doing plenty of research. I went to visit a couple days ago and he was so cute and I was really excited and they ruined it a little. 
AIBU for thinking my ILs are being far too negative and are making it seem as though the world is about to end? Should I change something about the way I'm planning to keep my dog? Experiences and advice appreciated.
