Thanks Mr Dinkar ,
In our colony we have 2 type of ground one for small children to play and the other open play ground this is vry big .
i cant take him to the small garden as there are small children playing who r afraid of big dogs plus if he does potty there it will mess the place.
the other ground is big and open , vry nice for long runs ,but some stray dogs are staying there ,they are frndly with chinu but me afraid of infection and ticks .
my house is a 2 bhk flat with vitrified tiles i cant make him exercise at home as he slip on the floor
