Hi Mary, I feel we know each other through Miss Gypsy..I foster, and my advice would be for you not to do it, unless you are totally dedicated.. It is more than a lot of work.. It is all consuming and my personal pets have suffered... I would especially be concerned for your older dog.. and the younger one's may learn some pretty , not so nice habits.. It does affect your personal pets, and in my case it hasn't been positive for them.. This is just my personal opinion, and it could be totally different for you, but I would give a lot of thought to your decision.. My personal pets have changed dramatically, and that makes me sad.. They are distant and fearful and they were never like that before.. Not to mention the work involved is huge.. I do laundry in the form of pee pads and at minimum of three times a day.. The cost of food is huge, and also the cost of tcertain medical needs fall on me also..That is huge.. You take them to the doctors, you give them meds.. They cme in from shelters covered in Fleas and ticks.. They are usually not house trained, so you are constantly changing diapers and belly bands.. They fight,, Some of them can be terrified of human contact, they bring in things like kennel cough and your dogs will get it..
On the positive side, they need you so much, some are so sweet and gentle, some are so cute, some actually use a pee pad or go outside..It's a thrill to see them put on a little weight and start to play.. Some have never had a toy even.. Some love to cuddle, and all of them find a good forever home where they will be loved and safe forever..Now , if you're ready to dedicate yourself to this end, then it's meant for you to do.. It's a big step... I h ope this helps in some way...
