select 
    ' my SQL Output '
   ,  Ownername
   , Count(DogName) as NumberOfDogs
   , sum(case when Vaccine = 'Yes' then 1 else 0 end ) as DogsWithVaccine
   , sum(case when Vaccine = 'No'  then 1 else 0 end ) as DogsWithoutVaccine 
from 
   @Starting_Data
group by 
   Ownername


declare @Starting_Data table (Ownername varchar(200), Dogname varchar(200) , Vaccine varchar(200) ) 

insert into @Starting_Data Values 
('Didi','Bruce ','Yes'),
('Didi','Dan   ','No'),
('Didi','Dagi  ','Yes'),
('Guy','Mika   ','Yes'),
('Guy','Blue   ','No')
