Further, we regularly offer tattooing at obedience classes. Dogs come out of class, are tattooed, and return to class with no loss of attitude. Skin varies according to the individual dog. With a dog the size a Great Dane will become, it is necessary to consider that possible stretching of the tattoo may occur with growth. Therefore, it is advisable to make the tattoo on a 7 week old puppy as small as possible.
Some tattoos stretch minimally, some a little more.
My policy is to guarantee the legibility of the tattoo. This means I will touch up any tattoo I do should it ever be unreadable. Occasionally, this becomes necessary, but it is so much better to re-touch later and have the protection provided from the earliest age. Tattoo prices vary depending on the tattooer and the registry used. Both registries have rates for multiple dogs and the tattooers generally charge a reasonable fee to apply the tattoo.
