You will need a 6-foot leash and a collar. If your dog is in the habit of pulling, he may be able to easily slip out of a regular flat buckle collar. are another option. These collars are ideal for training a dog to walk on a loose leash. They look like regular flat collars but have an extra loop that pulls tight when your dog pulls to keep him from slipping out. You should also have some treats handy.
Need to see more examples of leash training with different dogs
I have a cocker spaniel rescue dog which I have had now for over a year - he is red colour and is now 18 months old. Hunter has had issues since we got him in that he growls if you go near his toys, food etc he is clearly resource guarding. However during the time we have had him his behaviour has worsened. He now chasing lorries, vans and buses, he growls for no reason whilst in the home, he has snapped, growled and 'gone for' all of us, never actually bitten but I suppose the threat is there.
Hunter has been to training classes when we first got him and was great however became food possessive with the treats and therefore aggressive towards other dogs. We felt this made him and his behaviour worse so after the course completed we never signed up for the second course.
We have had a behaviourist out to him who surmised that his behaviour was nothing to with cocker rage but more fearful dominance and she provided us with some exercises to do with him that, to be fair worked. However, over the past 3 month as his behaviour continued I started him on Kalm Aid after the advice of my vert. Hunter has also had the plug in diffuser and the collar none of which have helped. Recently I went back to the vet with him as I was at my wits end. There had been a situation where I had fed him in the morning and my son was ironing his work gear and I was stood near him, Hunter began growling and snarling and basically I was scared to move. I advised the vet that we had tried everything and that he is walked during the week 3 times a day for around 50 minutes a time and at weekends about 4 times a day sometimes one if his walks if around 6 miles, so it surely cannot be not enough exercise. The vet prescribed some anti anxiety drugs which seemed to be working however he has been on these for 3 weeks and seems loads better but we have had two episodes of the growling and snarling the most recent last night. He was lay on my knee (not in his normal position) and he started growling, I talked to him softly to reassure him and my lads talked to him, I tried to move him from my knee but he growled and snapped at my hand, although I could feel his teeth on my hand he didn't mark it. This went on in total for around 10 minutes, he was pushed down but in doing so caught my hand, indented it but he has not left a mark. Whilst all this is going on Hunter is still wagging his tail although his body is stiff! Any ideas what more I can do, he is beautiful mostly well behaved and loveable dog but I actually do not know what else to do. Please help me, any hep/comments/advice would be greatly appreciated.
Dog Obedience Training: Introducing Your Dog to a Lead or Leash
The items you will need for training your dog to walk on a loose leash are: a flat, buckle collar; 6 foot leash; and plenty of small treats. Regular harnesses that hook on the back of your dog are not recommended. These types of harnesses can actually encourage your dog to pull harder. If you do want to use a training aid, then the use of a head halter or front hook harness is recommended.
