Calming supplements for anxious senior Pomeranians

Separation anxiety is one of the most distressing things to witness — for the dog and for you — and I want to be upfront: products can genuinely help, but they work best alongside a behavioural approach, not instead of one. Before I point you anywhere, I'd love to understand what's going on a bit better. How bad is it — mild whining, destructive behaviour, or full panic? How long has it been going on, and what have you already tried?

That's really helpful context — and honestly reassuring that your vet has already done the detective work. New-onset anxiety in a senior dog with no pain or cognitive cause often comes down to subtle hormonal or neurochemical shifts that happen with age, which is exactly where certain supplements can make a meaningful difference. A couple of quick questions before I recommend anything: is Biscuit on any medication at all, and roughly how much does he weigh?

Perfect — that makes this straightforward. For Biscuit specifically, I'd recommend Zylkene 75mg capsules by Vetoquinol. It's a casein-derived supplement — casein is a protein from milk that has well-documented calming properties — and it's one of the very few products with genuine veterinary evidence behind it rather than just marketing. The 75mg dose is made for small dogs exactly like Biscuit. You open the capsule and sprinkle it over food, so no wrestling involved. It typically takes one to two weeks to show an effect, and it's safe for long-term use with no sedation side effects. Because your vet has already greenlit a supplement trial, this is the one I'd go to first — it's what many vets reach for when they make that recommendation. You'll find it easily on Amazon UK. Run it for at least three to four weeks before judging whether it's working, and pair it with very calm, low-key departures — no big goodbyes or hellos — to give it the best chance.

Great question. Zylkene can be used either way — some dogs take it long-term at a low daily dose, which is perfectly safe, while others use it as a support during a training or adjustment period and then taper off. Given Biscuit is ten and this seems to be an age-related shift, I'd personally lean towards keeping him on it ongoing if it helps — it's gentle enough that there's no downside to that. But have a conversation with your vet after the trial period; they may want to reassess depending on how he responds.

I hope Biscuit settles quickly — six weeks of this is tough for both of you. Do keep the behavioural side ticking along too: short, boring departures, building up duration very gradually, and ideally a camera so you can actually see how he's doing rather than guessing. The supplement and the behaviour work together really well. Good luck with him.
