How inviting it must look to him. Now if he was a true country dog, he would be off leash and splashing around with the ducks.
As far as collars go, they are bad for small dogs. Invest in a no choke step in harness, as they don't come near the throat.
Some trainers even ask you to buy a choke chain. Do they really know their business. My Zada has a collapsed trachea, and because she's unable to breathe properly, it's putting a lot of stress on her heart and lungs. There isn't anything that can be done except give her medication every day for life to relax her. She's not allowed to go for walks because of the dust and dirt and I have to make sure I don't dust, vacuum or clean when she's in the same room. We took up all the carpets and had wood floors put down. She wheezes all the time and the symptoms are just like asthma. She won't live to be a senior because of this condition.
