"perfectly okay for an encyclopedia. ) - However British subjects require British spelling, etc.   
I have removed the word ""amazing"" from the caption.  
I'm not sure what the point is in complaining about American spelling.  Either way, one of us is going to have to adapt.  In this case, it's our British (and Commonwealth) cousins; in other cases, it's the Americans.  It's not worth complaining about.    
Wikipedia:Manual of Style says, ""The English Wikipedia has no general preference for a major national variety of the language. No variety is more correct than the others. Users are asked to take into account that the differences between the varieties are superficial."", and says, ""When either of two styles is acceptable, it is inappropriate for an editor to change an article from one style to another unless there is a substantial reason to do so (for example, it is acceptable to change from American to British spelling if the article concerns a British topic).""  See also Wikipedia:Manual of Style (spelling).    

 Feral Dogs 
Something about what is said about feral dogs in the article doesn't match with observations on feral dogs. Actually it doesn't even match with some articles in wikipedia. E.G. the Dingo is a feral dog too and they are excellent hunters, as well as the Carolina Dogs, who even seem to have some unique hunting skills. It's also wrong to assume that feral dog packs lack the social structure of wolf packs, you should browse for ""Tuscany Dog Project"" (thats a study concerning this topic) and the dogs there, although not completely feral, have a very complex social structure in their pack (check the german version of wikipedia if you like, there's a full article). Also wolves don't form packs on general, in Italy and in Germany as well many packs only consist of the parents, their current litter, and the litter of the last year. In Italy, there are many solitary wolves and many who only live in pairs, as well as quite a few packs of feral and semi-feral dogs who can hunt prey wolves aren't capable of and who are competing or interacting with wolves (depends on the situation). So all in all feral dogs aren't that poor.168.224.32.15  

The dingo has had thousands of years to revert back to a semi-ativistic state. Domestic dogs havent had that amount of time to become fully fledged wild animals.

While domestic dogs do form packs, there is little monogamy, cooperative hunting, or mutual puppy care.129.12.200.49  

In all cases? If known cases of adoption, care for puppies by aunts (I admit, there is no prove for care by males), monogamy and cooperative hunting. As a matter of fact, these things aren't as common among wolves as most people think. Don't you think, you generalize to much?
E.G. Erik Zimen (a famous cynologist in Europe) witnessed no monogamy in his poodle group. Observations by Eberhard Trummler and Elizabeth Marshall Thomas came to different results (the first observed dingo/wolf/dog-mixes and the latter Sibirian Huskies), as well as Guenther Bloch in his studies in Italy (two groups and one pack of near-feral dogs, mostly or entirely mongrels). You should keep in mind, that there isn't much data concerning this topic and it wouldn't be the first time that an observer didn't really observe and just judged by what he/she already thought to be true. Remember, for a long time people thought, that wolves would generally form packs with an alpha on the top and an omega on the bottom of the pack or that dogs would always search the nearness of humans, because ""they are born that way"". Both ""Facts"" have been proven to be wrong since at least the 80's, although they are still in the mind of many people.  

Laughter in dogs?
It seems like the whole paragraph was POV and/or derived from unreliable sources, so I commented it out for now.

 Dangerous substances 

Other than the danger of toxoplasmosis from eating cat feces, does any real harm result from dogs eating feces? If so
