1: Is your dog microchipped (I'm pretty sure less than 5% of the population is tattooed at this point)? If so, what company? Do you keep the information up to date? **Both of the spaniels are microchipped. Neither were done by the breeder. Both were implanted at a low-cost clinic (the same time they took/passed their CGCs). The company is HomeAgain. I do keep the information up to date. It took me a month, but I just put our new address/info on there. I do not pay for extended services, they are only registered. 2: Does your dog wear a collar with ID? If so, when? What other tags, if any, are on the collar? **In the winter they wear rolled leather collars (longer fur) with a name/phone number tag, rabies tag, and microchip tag. When they arrive, the license will be added to that. Just today I put the micro rubber bands around the tags to eliminate jingling! I don't know why I didn't think of that before. In the summer I rotate between nylon collars. They don't typically wear collars in the house. 3: If applicable, do you keep your dog licensed? 2/3 of the places we've lived, licensing your dog is "required by law." The one place it wasn't, only dogs declared dangerous had to be licensed. All have required Rabies immunity in some form (some accepted titers, some didn't). Where we live now they have different options for licensing and I like it (lifetime, potentially dangerous, dangerous... none are by breed; only past history). I am sending out a Rabies titer on Buzz (because my current vet likely won't write me a "your dog has had a vaccine every 3-4 years his whole life, he's almost 14, he's got enough immunity" like my friend's vet did) and the city will most definitely accept that! Hooray!
