Dog Training Ireland, off the Blanchardstown exit of the M50. What you need to look out for is that anyone you trust to train your dog uses positive reinforcement methods only. I’ve had my DID dog with them from April to July on and off for formal training and have found them great.
"Do no harm"
My older dog had nothing like that in his younger days so he unfortunately had some harsh training with a local vet’s trainer (choke chain) and lemon spray in the face through a trainer we had come to the house (and she’s still verty much on the scene as I see adverts in the local vets). I saw for myself the negative impact it had on him and promised myself I’d not make the same mistake on the new fella.

Good luck with your choice.

We want to sign in for training classes too. I’ve sent an email to DTI in regards to their next Level 1 training as all courses currently are running. I’ll let you know if I’ll get any reply back.

my pup hailey did the puppy socialisation class with dog training ireland she loved it and will soon be starting doggy day care 1 or two days a month for socialisation and fun

I can recommend the training classes with the DSPCA. They run courses that are an hour a week for six weeks and I found the trainer Alex to be great.

Plus I like that the profits are going to an animal welfare organisation. They are based in the Dublin mountains near Rathfarnham, so it might not be suitable for everyone.
