My Jilly topped out at 3 lbs. but she was a runt of a litter of larger puppies. She had terrible medical problems along the way, especially after she got older. If she even jumped off the bed or accidentally fell off the bed or couch, it required a vet visit to be sure she was okay & had no fractures, etc. Once a jump down her doggie stairs dislocated her shoulder when she was 12 because she missed a step & landed hard. A larger, stronger joint capsule would have taken the force but not hers. The vet suspected she had stressed/torn the joint capsule from repetitive jumping over the years & weakened it over time. If you want to get a tiny, be prepared to deal with the financial aspect of it - and all the time it will take to deal with the various health-related problems, vet trips, sleepless nights, etc. Tiny dogs are very special & do find a special nook in your heart but just be mentally & financially prepared if you do get one. I'm sure many tinies make it through life with no or few special problems but fear they are in the minority.
