Yes and No,
Most animals indeed only form bonds of affection for their own purposes, they form groups for hunting or surviving and need displays of affection to keep the group together. Whether this is love is debatable, but primates display similar behavior to our own displays of affection.
What we usually call love is mostly a hormonal thing, you choose your partner based on the chemical mixture that is in his or her distinctive body scent. (Not going into detail here, no expert on these things XD) So, if that's what we call love, then yeah, it's the same in the animal world, just because we (think we) are higher developed than most animals our feelings paired with things like infatuation seem more complex and deep. Though it is a fact that animals can feel our emotions, and not all of them take advantage of our states of weakness.
Easy example: The dog.
They started hanging out with us millions and millions of years ago, because we offered easy food and shelter. And in return, they became our companions. A 'good dog' won't leave his 'owner's' side for a minute, will protect him with his life and bring comfort. They feel our emotions and react to them.
A lot of people will tell you that when something really bad happened to them and they were deeply depressed or sad, their pet came to them uncalled as if to try and comfort them. This does sound a lot like love. It is behavior without much benefit for the animal (as most dogs actually don't really benefit from cuddles and hugs as they do from petting which resembles the grooming of their mother).
So, I don't really know if love would be the right word, but that's what I'd call it.
