Concerning Archer's forthcoming agility lessons:
You might want to check out the boards concerning this. I'm not an expert on the subject, but I've been told by a lot of bc people to limit my pup's activities (I have an 8 month old) at least until she's a bit over a year old. I've been told that agility and frisbee (and anything else that causes the dog to physically push him/herself, flip around, stop suddenly, etc) can be harmful to your dog's physical development- and it's best to wait until your pup's body is done growing before starting agility + dog sports.
My pup is a bit like Archer- she'll play a mean game of fetch indoors, and drop the ball directly in my hands- but she doesn't share the same zeal for returning the ball when we play outside! I think it's a maturity thing- my dog seems more distracted outside.... more smells, sounds, etc. I don't take it personally, lol...I think the bc attention span improves greatly with age.
I hope that you're enjoying your pup! I've discovered a few things that help to keep my pup happy and calm and help keep me sane- particularly on days when it's impossible or impractical to have a long outdoor exercise stint. I thought I'd pass them on in case you might find one of them useful.
1)Sometimes I'll load a kong with Evo dog biscuits- they're the perfect size for kong stuffing, and they're healthy! They're just difficult enough to get out of the dental ball kong I have- certainly not impossible, but hard enough to keep my dog busy!
2)If she seems like she could use some exercise, and someone else is home- we play a short (maybe ten minute) game of "doggie in the middle" with a tennis ball. I don't encourage her to jump/twist to get the ball - I do some easy throws back and forth... eventually I'll let her catch one to keep her interest (and sing her praises as she returns the ball!). Sometimes I'll roll one... or I'll fake her out and let her try to figure out what happened to the ball! The variety helps keep her interested in the game and helps to stimulate her mentally, and the short burst of energy needed to keep up with the game tires her out quickly.
3) If puppy is especially fussy or seems potentially destructive - a nap/time out in the crate may be in order. When mine gets naughty at night- it's usually because she's ready for bed.
