Just back (in tears) from a lovely local dog walk. Out with family and our 4ddogs. Saw a dog extremely like one we fostered 2 years ago, sadly he had a breakdown at his new owners and was pts soon after. Ddogs all 'recognised' this ddog despite not seeing our ddog for about 20 months. Must have seen 100 dogs today and all reacted to this one only.
Is it possible they 'recognised' and remembered from that long ago?
I know dogs know things by association, lead =walk etc but a real 'memory'? Quite blew my mind and made me bloody upset!!. Rip Oscar and Merry Christmas.
