My wife lost both of her parents last November. My daughters think a little dog might be the right tonic to give her some companionship and exercise. I'm still on the fence about this...I know they are a lot of work. But I am semi-retied and there are 4 of us. Hmm...
I don't recommend you get any dog without having several long heart to heart discussions with your wife. Both of you have to really want a dog in the house, and be ready for the daily walks, vet expenses, and other responsibilities involved. Unless she is really excited about getting one, I would not bring a new pet into the home.
I have a labradoodle and I have to say that any poodle mix requires high maintenance in the grooming department. I groom my own dog, and it's a never ending job. I'm not fussy about his appearance in general, but the hair grows constantly and within two weeks his eyes will be blocked with hair, his hair will start matting and tangling even with frequent brushings, etc. I don't trust professional groomers, but unless you or your wife is willing to pay for grooming, probably on a monthly basis, or do it yourself, a short haired dog is the better option.
Consider that some, not all, small dogs can be barkers, which may be an issue in your house, yard or wherever the dog is. Some breeds are more vocal than others too.
Some breeds are more active, nervous, demand more physical exercise than others. I love dogs (and cats), can't imagine not having a pet or two in my home. Of course if we are too old and sickly in the future, we'll have to do without.
I suggest you do your homework, research different types of dogs, but most importantly, make sure you are both on the same page, both excited to bring a dog into your family, and both willing to do all the things necessary to make a happy family with little stress or turmoil. Also, you should both be involved in the purchase or adoption of a particular dog. Spend some time with him/her before you bring them home.
Good luck! I didn't take the poll, because until your wife weighs in and you have considered it a bit longer, hard to say yes or no.
