Ringo was fine the next day but we do find he has spells when he is really hyper for about half an hour where he wants to play all the time then he wears himself out and falls asleep, Stig used to do the same and he was a nightmare but because Ringo can play with him its not so bad. I'm going to put treats in small cardboard boxes and old Butter cartons if you put some in a toilet roll press the ends in and he will chew it up and the treats come out , these will keep him amused trying to get the treats out and it mentally stimulates him, that also tires them out. I used to find that Stig was most tired when he started his puppy classes , he would come home and flop out really exhausted.
Liverbread it easy to make and you can chop it up and freeze in little bags they both love it and its good for training. I post you the recipe I use if you want.
