7 year old border collie behaviour

[AddictedtoGreys]

Hi, does anyone here have any extensive border collie experience? I have a male castrated border collie who is 7 years old, had him since a puppy. He's not a working dog. Over the past couple of months his behaviour has been getting progressively worse. For example...going absolutely ballistic if someone knocks the door to the point of rushing at me and biting my clothes today, nipping my DH hands and legs when he leaves the house, if me and my DH and in deprecate rooms he paces between us getting more and more wound up whining and barking very high pitched. I have an appointment at the vets on Wednesday to make sure it isn't an underlying medical problem, but has anyone heard of a dogs behaviour getting worse as he gets older? No changes at home in the last few months either

*me and my DH are in separate rooms

You are right to get him checked out by the vet. Any noticeable change in behaviour does need to check out asap.

Is all this behaviour totally new or is it behaviour that has been noticed before but has escalated?

Nippong when people leave is a very common collie behaviour (based on the herding instinct ) but it is unusual to start at 7 years if nothing else has changed. There are strategies to deal with this but you must get a clean bill of health from the vet. I would be worried if this was all totally new behaviour if it were my dog

Thanks for the reply.

Yes totally new. Started a couple of months ago, so I thought maybe it's boredom so we increased his exercise but if anything it's gotten worse. He will probably have bloods tomorrow at the vet so fingers crossed its nothing serious
