My son is like this too. He goes compeltely manic after tea. He comes out the bath and he turns into a kangaroo, he actually can't walk, he bounces, spins and gyrates around and has developed a strange laugh that just goes on and on and on. He flings his head around and it's so hard to get his hair dried and into pyjamas. He calms down for story then it takes about 4/5 returns to bed (toilet/water/there's a lion in my room/taken my trousers off/kicking the wall as he merrily screeeeeaaams).
But we are very firm. Back to bed, night night. Back to bed, night night, back to bed, night night. Worst thing we could do is engage with him, he's so talkative and any interaction just "wakes him up" and he's off again.
I recommend - explain during the day and remind at tea time: that bedtimes will be different from now on. It will be boob/one book/cuddle then bed. No toys, no annoying dogs, no climbing on you. Into bed and stay there.
It might take countless returns but you have to almost be like a shut down robot - no talking, no exciting facial expressions just a deadpan "night night, see you tomorrow". It's hard but they need a message that they won't be getting any attention (barring basic things - nappy change or hurt etc) until they've have their sleep.
I'm not preaching, I know how impossible toddlers are, and we can't make them sleep! All the best OP.
