i have had a dog for 7 years. for 3 of those years he was painful to be around. he chewed whatever he liked, he wouldn't behave on walks and spent all day badgering the whole house to get them to play with him. after a long time of thinking i had him neutered and he still didn't behave. even though i was certain that would calm him down and make him manageable it didn't do enough. so i got a dog trainer, i devoted more time to entertaining him, i put extra effort into teaching him how to behave and now he's the best behaved dog in the world. i used to cry at walks because he'd just pull me over and never once would i have considered abandoning him. i considered selling him to a friend on only one occasion. how you can just leave a dog because they're difficult is beyond me. it's so cold.
