When giving recomendations about things with animals, its really best to go off experience.
Not to really tell people, "hey, this is what I heard" or Joe Blow said because you do not know what could be true or wrong. You very well could be giving out misinformation. Anyone can go and read on the internet about things. And I believe the op was asking about just that, people experiences with them, not what someone has read or heard.
I personally disagree with this. In the fox forum, many of us share information that we have learned from each other in the past. Most fox owners only have one fox, so they collaborate with other owners to learn about what traits may be species-specific rather than an individual's trait. I think it's very important that we share and pass on this information. If we didn't, all of us would know a lot less about foxes and would likely not know what to expect when we get our own fox.
I agree that you do have to be careful about what you believe and pass on. Use discretion, learn what people are like and trust those who have been reputable in the past.
I'm not saying that information Splashstorm was giving is correct nor incorrect as I know essentially nothing about wolves and wolfdogs, just commenting on the concept of only sharing information you acquired through experience.
