Loki's Training Plan

A 6-year-old Jack Russell • for Victoria & Ryan

How to help this wholesome little menace to shut the fuck up so V can froth over Agent Hotchner in peace.

The one big idea

Everything on this page comes back to three simple rules:

Tip: pick just one or two problems below to start. Don't try to fix everything at once.

Barking at birds, cats & people outsideInside the house and at the window
Why he does it: Jack Russells are born to watch and shout out. Loki's brain yells "something's there!" before he can stop. We can't switch that off fully — but we can make it shorter and calmer.

The plan

How long: about 8 weeks for the sounds, and up to 3–4 months in real life. He may always give one or two barks — that's okay. We want fewer, shorter, calmer.
Don't do this:
  • Don't shout "quiet!" — he thinks you're barking too, or that shouting means attention.
  • Don't sit him in front of an open window full of birds to "get used to it." That makes it worse.
Barking at bikes & skateboardsOn walks, at moving wheels
Why he does it: Wheels move fast, and Loki's hunting brain wants to chase. Once that brain switches on, he can't hear you. Chasing feels so good to him that it's a strong habit.

The plan

How long: this one takes longer — about 4 to 6 months of short, regular practice. Chasing is deep in him, so be patient.
Don't do this:
  • Don't yank or tighten the lead when a bike comes — he feels your worry and reacts more.
  • Don't let him chase and pull. Every chase makes the habit stronger.
Fighting with other dogsOn walks — sometimes, not always
Safety first: If Loki has ever bitten and broken skin, or fights often, please see a vet behaviourist before trying this yourself. See the "See a vet" section below.
Why he does it: On the lead, Loki can't move away or say "back off" with his body. That makes him frustrated or scared, so he barks and lunges first. Terriers also fire up fast and are hard to stop once started.

The plan

How long: about 4 to 6 months of regular practice. Go slow — one scary close-up can undo weeks of work.
Don't do this:
  • Don't hold the lead short and tight — it makes him pull and panic more.
  • Don't practise where loose dogs can run up to you.
Whining & tapping the bowl for foodAt meal times and when you eat
Why he does it: Because it works! Somewhere along the way, whining or tapping got him food or attention — even once in a while. So he keeps trying. Terriers are stubborn, so expect him to try harder before he gives up.

The plan

How long: a calm mat takes about 4 to 6 weeks. The whining and tapping fade over 8 to 12 weeks — but only if everyone sticks to it.
Don't do this:
  • Don't give in when he gets louder — that teaches him louder works.
  • Don't let kids or guests slip him food from the table. One treat resets the whole thing.

Food & keeping Loki trim

Loki's carrying a little extra weight — and a hungry dog whines more. Here's how to keep him full on fewer calories, which helps the whining too.

What's the best food for Loki?

Whatever style you feed (raw, cooked, or good-quality packaged), the golden rule is that it must be "complete and balanced." That means it has every vitamin and mineral he needs. Home-made and raw meals often miss some, so ask your vet to check his menu. Here is the simple shape of a healthy bowl:

Always: fresh, clean water.
Never feed Loki these:
  • Chocolate, grapes and raisins, onion and garlic
  • Xylitol (a sweetener in some gum and peanut butter)
  • Cooked bones (they can splinter) and very fatty scraps

Loki is a little overweight, so ask your vet for his exact daily amount to lose weight safely. Feed him to his ideal shape, not just what the packet says.

Handy ways to keep him full and trim

Never do this

These feel quick, but they make things worse. The science is clear.

Reward-based training wins on every measure: less stress, faster learning, and far less aggression.

Call a vet or behaviourist if…

A vet behaviourist is the right person for serious cases. There's no shame in it — it's the fastest, safest fix.

Where experts don't fully agree

We want to be straight with you. Good science still has a few open debates:
