Is a teacup dog good for breeding

Teacups and miniature dogs are not very good, as they are small and their food intake is not easy to control, so feeding them too little can easily cause them to be stunted and thin. Feeding too much, the dog may suffer from indigestion, flatulence, diarrhoea, etc. At the same time, they have a weak resistance and are prone to other diseases, which are also more difficult to treat.
