Everyone's posted the pros, so I'll go with some of the cons that made me tear my hair out for the first few months:
Biting, biting and more biting. There were weeks on end that I just went through the motions of taking care of him because his biting was driving me to my wits end. You couldn't touch him without him using your hand as a chew toy. You couldn't walk around the house without him nipping your butt or pulling on your pant leg.
They are STRONG! Harvey's only 5 months now and it takes all my energy to walk him on a leash. He pulls and pulls, he jumps up on me and strangers (and knocks smaller children to the ground) and I get angry with the situation and don't find pleasure in walking him. He's slowly learning, but it takes a LOT of hard work and teachings to get them to stop pulling on walks. The strength they have from an early age is phenomenal.
They don't like to be left alone. While Harvey has slept in his crate alone every night from 7weeks until 20 weeks (he occasionally sleeps out of there now) he hates being left alone when I leave for work. He calms down after a bit but he wants attention and company. 3 hours on his own is all he can handle, if that. You really need to have someone who is home the majority of the day if you are going to get a Golden, they are not the type of dog that are happy to stay at home alone a lot. Even around the house, they love to follow you around, sit next to you while you're cooking, lay next to you while you're watching TV, bring you their toys when they want to play.
They love EVERYONE! People, dogs, other animals...Harvey doesn't seem to understand that not everyone appreciates him jumping up on them and kissing them, not all dogs want to play with him, some smaller animals are scared of him and he can hurt them without realising his own strength. This is an ongoing issue as I am trying SO hard to train him but it's a long, hard road.
They are inquisitive. Oh my god, are they inquisitive. He needs to investigate everything, sniff everything, lick/eat everything, hear everything, watch everything. Sounds cute but when you can't put a glass down without him wanting to "have a go" it gets tiring. Again, training issue but a tough one.
Sock obsessed: After having him home for nearly 4 months, I officially have no matching socks left. I constantly find underwear and socks of mine hidden in his bed, blankets, under the couch, even partially buried in the garden!
But you know what? Those traits make up this wonderful breed! And yes, I'm biased, but a annoying as some of them can be (are) I wouldn't change this monster for the world
