thankyou to all that helped me with Toby my 6month old lab,
i WAS having trouble with him pulling on the lead, and his trainer told me to use choker but it was choking him,:-(
i bought a halti and security link as lots of you advised,
im please to tell you it worked instantly, and not only that he now sits and wait at curbs,
walking him is so much fun now, i never thought it would work so quickly.
THANKYOU SO MUCH :-)
