As many as you can handle.
I'd like 2 or 3 bushing types and 3, 4 or 5 running dogs. Ground depending.
I have 1 cover smashing Bull x, one Springer Lakeland and a very useful game obsessed Malinois. Just lost my Grew the a park bench and a working Mastiff to a nasal tumour.
Now I am looking for one general purpose running dog and a new bushing dog. My husbandry will only allow me 5 dogs, to much shite to pick up etc .
