My 10mth border collie x lab keeps running round house doing same circuit . I worried something wrong !

Yes there is.  He is distraught as he has not been given enough to do.  This is a working breed and the most highly intelligent of all breeds.  He is not a pet breed.  This circling means he is suffering mentally. 

It is essential that he is given brain exercise.  Some people assume that they can wear the breed out with loads of walks.  Nope!  The dog is built to work sheep, so could work all day.  So walks don't cut it for such an energetic, intelligent breed.  He is working his brain when working sheep.  If you are not going to give him what he is bred for than it is up to you to give his brain some exercise.  If he is from a reputable breeder then perhaps they could help you devise some search games that, once developed, can be used at tracking.  This is much enjoyed by the breed.

Have you taken him to training classes?  If not then enrol with a reputable obedience class - but only reward based training.  Punishment is not the way forward with such a highly sensitive breed.  They can get very upset if they get any commands wrong, so it's best for you to be trained how to do it properly. 

We do have some very good trainers on CD and hopefully, if one of them sees your post, they may be able to help you further.  Just noticed, this is a Collie cross, but as the cross is with another working breed, most of this will apply. 

Thanx for advice

Everything Jean has said!  In my experience of this cross (I have one and know many and have worked with many), they almost always take after the collie parent, and strongly.  So treat them as if they are a purebred collie - lots of mental stimulation, work that brain and he should settle down a bit.  Do also remember that while he may look grown up at 10 months, he is both a puppy and a teenager so will still be very energetic - he's not mature by a long way yet!

Based on the Elkhound collie cross litter friends and I re-homed, whose mother I bred it's the collie that is uppermost in collie crosses.

This pups now a year old are nothing like the bright but easy going Elkhound parent, except to add stubbornness to the mix.

And I remember you telling us about how it all came about.  Good for you helping to sort someone else's headache, but Barbara - you must have been horrified.  I felt so sorry for you at the time.

I was, my experienced obedience friend who is collies first but always had something different to keep her grounded and had an Elkhound bitch returned to me at 7 months says it was potty.

She took on one of the bitches, but she now sort of belongs to her sons OH who lives close by, as since her season she has wanted to kill the pathetic Yorkie neutered male.  Now that's not Elkhound at all. 

I think the hunting and the chase instinct are in there and she has been a much harder play biter than any Elkhound, and the one she had was spirited.  She'd defend her compatriots if any dog tried to bully/attack them.  She once faced of a large staff type from attacking her elderly male collie.

Hear a few people make comments about this being a prime example of "Bored Collies" and it really hacks me off.

Nearly always find they're on the back of a simple one line question and without asking for more info about the dog and it's lifestyle / exercise etc.

Yes - it may well be the case in most but not all.    I also have a 10-month old who is active, on the go and has various jobs at home and around the farm from 6am but as a younger puppy she also had mad bouts now and then of dashing all over the house like a lunatic.  Only lasted a few mins and tended to happen more often than not when she'd just been showered and / or if we'd been very busy and she was in a sort of "overtired toddler" mode. 

It's lessened as she's grown older and rarely happens now but I just had to wade in about the "Not doing enough / it's bored" remarks. 

My collie X did this every evening after tea no matter how much physical and mental exercise she had.   She did this up until the day before she died at 17 years old.  I quite liked watching her showing how much she enjoyed life.

My pup also has a mad 10 minutes after tea. He's no collie in him and I now feed raw, so its not that either.
  I just think they're glad to be alive (and I possibly ☺ encourage them)

Unless it's excessive and/or obsessive I wouldn't worry.
