Totally agree, my Collie is a rescue from working strain, dumped as a 6 month old, she's now nearly 15yrs. She took some considerable time to house train and once settled took a great deal of work to 'get right'.
She needed loads of 'jobs' to keep her happy and out of mischief, she had in her younger day a massive desire to chase, catch and return to me, so the ball became her prey.
Her food used to be hidden in kongs and under light bowls that she had to work at to get, her toys had to be taken out of the toy box and returned to the box by her, her job on walks was to carry the ball and when allowed she had to drop it at my feet and wait for it to be thrown then when told she was allowed to chase retrieve and return with it, this could go on for hours for her and she'd never tire unlike me!!
She was also a great swimmer and would retrieve the ball, back and forth back and forth, it kept her fit and happy and not quite worn out!!
She also benefited from long lead walks in very busy places heavily trafficked with people and cars when she was not allowed off lead.
Collies are special dogs and not for the faint hearted, they need a busy owner IMHO.
The OP's pup just sounds like a typical collie pup to me, keep it busy whilst being aware of it's age, make it work for all of it's pleasures, teach it tricks and games, just give it something to do, I'd say.
