Brain Support for Aging Border Collie

A 14-year-old Border Collie showing cognitive changes — that's a really specific situation and you're right to take it seriously. Border Collies are sharp dogs their whole lives, so when that starts to slip it can feel quite jarring. Can you tell me a bit more about what you're noticing? Things like staring into space, getting confused in familiar places, disturbed sleep, or just seeming less 'present'?

That pattern — the night waking, the blank staring, the general fogginess — is very consistent with canine cognitive dysfunction. It's essentially the dog equivalent of dementia. Is she on any medication or supplements already, or is this the first time you're looking at brain support?

Good — there's a solid evidence base behind one ingredient in particular for this: phosphatidylserine. It supports cell membrane health in the brain and has shown real results in studies on dogs with cognitive dysfunction. The product I'd point you to is Aktivait for dogs — specifically the large dog capsules, since she'll be over 10kg. It combines phosphatidylserine with omega-3s, antioxidants, and L-carnitine, which is a well-rounded formulation for exactly this kind of age-related cognitive decline. It's made by VetPlus, who are a proper veterinary nutraceutical company — not a wellness brand. You open the capsule and mix the contents into food, which is easy at her age when you don't want a tablet battle.

Most owners report changes in sleep patterns and responsiveness within four to six weeks, though some see improvement sooner. It's designed for continuous daily use — the benefits build over time and tend to reduce if you stop. It's very well tolerated; there's no known toxicity at normal doses and it's regularly used alongside prescription medications if your vet does eventually decide to go that route. I'd suggest logging her symptoms weekly for the first two months so you have something concrete to share at her next vet visit. It also helps you notice gradual improvements that are easy to miss day to day.

You're doing exactly the right thing. At 14 she's had a great run and clearly still has quality of life — supporting her brain now can genuinely extend that. Give it a proper six-week trial and don't hesitate to loop your vet in once you have some observations to share.
