Adding a second dog was the best thing we did for our chi Gino at the time. It gave him a playmate while we were at work/school. And since Gino was such a great doggie, like Lady, it was super easy! Yes you have to buy more food, so a 4lb bag that used to last 2 months only lasts 1, not a big deal. And yes, the vet bills are double, so if finances are the reason for the hesitation (I don't think they are) then that is something to consider. I agree that the benefits totally outweigh any risks. And since he's not a puppy, it should be even easier. To be honest, adding a third dog was the best thing we did, lol. Now if I want to only take one with me, the other two aren't alone.
Bryan didn't want a third chi at all, he was so against it, wouldn't even look at the puppies I found. So I said, forget it, I'm going to do what I want to do since I pay for all the food, toys, clothes, and most vets bills. Not even a week after we got Leo, Bryan couldn't stop saying how much he loved having a new puppy and loved Leo. Your hubby will fall in love, just do the trial!! Keep us posted!!
