It's me looking for reassurance, not Keely  I was sure i was going to be an overly-anxious mum where Keely's concerned because of what happened to Kintra but so far i've not been too bad! But now Keely's taken to collapsing after a bout of playing fetch.  I'm using a ball launcher for approx 5 minutes whilst out in the field a couple of times a day, and i'm randomly throwing the ball in the garden too but i wouldnt say i'm over-exercising her.  She will chase the ball approx 5 or 6 times then just drop to the ground in an exhausted way (always when she has the ball).  When i approach her she throws the ball at me and i generally end the game right there.  She always pants whilst running around too (something Kintra NEVER did for some reason).I'm sure there's nothing to worry about, i think it's just that she has boundless energy and an obsession with playing fetch and that she's just putting a lot of energy into it. I know some of you may be thinking "duh, that's just a pup getting tired from playing", but as strange as it sounds i'm not used to the panting or the obsession with fetch.  Does this all sound normal?

I should have titled this post "Looking for reassurance....AGAIN" - sorry, i seem to be quite a high maintenance fellow forum user  

Has the weather gotten warmer?

Mine pant all year round when they retrieve.
As for collapsing?
She's pooped - make the retrieves shorter - if it worroes you.
Persoanlly, I try to make the retrieves s long as possible in an attempt TO wear them out.
You could go for a cadio test.

Has she been tested for heart worm?
