I am thinking about walking dogs for a rescue group, as a volunteer, and they currently have 9 dogs in. I will walk all but one dog, as I find her much too strong for me, and if she senses "prey" she will go, and when I first walked her as a trial run, I gave her back after 10 minutes of her pulling and me not able to hold her. The volunteer who I was with, didn't even check her when she pulled, and just let her pull, no stopping etc. After that, I asked the rescue group, if I agreed to walk her, would it be ok if I used a halti? She is a SBT, and I use a halti on one of my friends SBT's as she pulls a lot. I was told that I wasn't allowed to use a halti, although it was my own, with my own training lead, as it was unfair on the dog. What are your opinions?
