It,s so frightening when it happens, think we've all been there! Well done for your reaction.
When we moved up to Scotland I took my two year cocker for a walk in the local wood and he saw a deer, first ever. He took off after it and Imheard his barks disappear into the distance. IMwas distraught as I did not know the area, and thought he would be lost. Drove around trying to find him, and he came home on his own about two hours later, his coat absolutely stuffed with burrs. Think he'd had a lovely time
One of my Scotties did the same after a squirrel, and I eventually found her in the car park, sitting next to a smart BMW instead of my old banger
Dylan did it at six months old, in woods again, whilst on holiday, and nearly got run over. Phew, what they put us through!
Glad your boy is none the worse for his break out
