One thing leads to another. This is about the question of how one can identify dogs among the various zoomorphic patterns, since there's quite a variety and they're not very lifelike...
So here's a little collection of designs I found.
Unfortunately, in my opinion the result is not very conclusive; though all dogs, I wouldn't bet anything to not confuse them with wolves, or any other quadruped, for that matter, since some of them rather look like a doe, or even a capricorn. Not to complicate things any further, they're all insular style, otherwise there would be an even broader range of forms.
The sources of the designs, starting at the top middle ("noon"), going clockwise:
1. The Strokestown Crannog, Co. Roscommon, Ireland
2. Christ Church Place, Dublin, Ireland
3. A slate from Dungarvan, Co. Waterford, Ireland
4. Lindisfarne Gospel, British Library, London
5. A Stone Cross, Dysert O'Dea, Co. Clare, Ireland
6. Lindisfarne Gospel, British Library, London
7. The North Cross, St Mary's Abbey churchyard, Duleek, Co. Meath, Ireland
8. Lindisfarne Gospel, British Library, London
9. Dungarvan, Co. Waterford, Ireland
10. Durham Cassiodurus ("Expositio psalmorum"), Durham Cathedral, Northumbria, England
11. In the centre: The Book of Mulling, Trinity College, Dublin, Ireland
All, again, found with the help of the books of Aidan Meehan.
