I brought him home yesterday evening and changed his name toRex (to know why, please see General "Would dogs be comfortable with names that for humans sound mean? thread from April,12. Sorry i do not know how to put the link here).

He didn't have anything: bed, blankets, towells, chew or squeak toys, only his leash. His eyes are so sad, that breaks my heart.
He has been very quiet. Neighbours said both former owners (both men, macho type), let him without food, physical activities, everything.

He pulls the leash a lot, but never barks or runs after people, cars, bykes, children, birds, joggers, etc. But he looses control when se sees (or smells, even at distance) another dog. He starts to bark and growls and jumps and pulls toward the other dogs. There are no commands that help. The only thing that helps a little is when i press his muzzle with my hand.
He gets better only when the other dogs are out of his site, the ones wich do not care about him. The other ones, will also bark and growl in response.

He does it to any dog, big or small, young/old, male/female.
At the end of "his scene" he howls, grins, whins and "pouts". After few minutes he is at his normal mood, till the next dog/dogs. Any help?

Because of this, I cannot take him with me anywhere, only to his walks. I already bought a Muzzle, wich he removes, and i thing i should try the Halti... But, at home he is a sweet lord.

He doesn't wanna eat, if he does, only a little bit. Many treats and toys were left ignored.

And he loves to be groomed and massages. And when i do at his chest and belly, it seens he goes into a kind of trance and even "purrs" with a smile.

As soon as i have pictures, i will post.

Thank you all very much.

Rosana

Rex, GSD, 3y
