I have cared for a number of dogs; all different breeds and all loved equally. Currently my two boys are a Great Dane and a Cane Corso.
My Great Dane (Pax) is a rescue. We got him 12 weeks from the animal welfare league. He has a very anxious disposition but is the most caring dog ever. My Cane Corso (Tiny) was gift to us. He is very hyper and loves attention and cuddling. Sleep is probably the hardest thing to do with my dogs (They both sleep on the bed and we don't get much room).
I also previously had a Staffordshire Bull Terrier (Midnight). Unfortunately, she passed away and has left us with a big hole that has been very hard to fill. I have also fostered giant breeds as well.
I can assure that I will take care of your dogs with as much care and love as I do mine. Owning giant breeds has given me a lot of experience with handling dogs and being confident around them.
