LO that's what my hubby says - and we have 6 living here!!
I think 2 is a lovely number, they are good company for each other. By 3, your whole life really revolves around them -and after that it just gets worse! By 6, not many people are brave enough to have you visit!! {yes if you count my signature it shows 5, but I foster a bitch for my friend, Tizzi}
Four is a really nice number - but still may be too many to take around with you.
On a more serious note, if you are considering adding to the family, please think very seriously about doing so - do you have time to look after that many dogs, space for them - we have just under 1/2 acre of garden here, so plenty of room to run around. One thing we don't like to think of but should be considered is FINANACES - not just purchasing the dog, but vet costs particularly - also feeding.
To give you an idea, it takes 2 hours to brush everyone properly...then two walks daily {unless hubby is around to walk with me - and we are very lucky in that we have many areas where we can let them run loose, it is nearly impossible to walk 6 on the lead together}. Poop scooping takes a little while - at least 2 poos each daily, times 6!! Well I'll leave you to imagine that...and do you have facilities to dispose of that?
Individual training and play times...probably as much as you can give - likewise cuddles.
Feeding - it takes about 1/2 an hour to get everyone's dinner ready - and then clearing up afterwards.
You usually have to shift someone to be able to sit down!!
And can you live with the extra dog hair - we vacuum every day, but there is still always dog hair around and in the air...
How will you transport them in the car? We had to have a cage specially made, from
http://www.dogcages.net/home.htm. It is excellent, and very quiet in use - I hate the ones that rattle! - but it wasn't cheap. We also have a divider, so have 3 in each side. We do also have a large car...
And lastly - but can be very important - can you and YOUR NEIGHBOURS cope with the noise? Hubby refers to them as a cacophony of Cavaliers - they are only really noisy if people are around {doing their job of alerting us, or walkies time.}
Having said all that, I wouldn't swop them for the world - they are the best incentive to get up in the morning, and you feel like you are the most loved person in the world.
