2 puppies or 1?

I have 2 Siberian husky puppies.  They are littermates and we have had them since they were 8 weeks old. They are now 7 mos old and the work is not unlike raising children.  It is a commitment.  If you can commit to caring for them, considering your sitch,  the breed you understand and what those animals require to become the adults you always will love and care for!
 
It is a lot.  I waited til my children were old enough to understand all of this and safety in handling.  The children are easy at this point and the concentration of training goes into the animals in this home. 
 
For Sibes, they need a lot of exercise, a  good area to horse around in and run their tails off, play and keeping it clean is very important too.  They need good health care, and it all costs money...  Good food is essential to find for your breed too.  And that is not usually what you find easily at your local grocery.  And that is $$ too!
 
They bond to each other, naturally.  And since we all love to play with them and work at training  they bond to each of us.  They look to me for a lot, like a mom.  I quite love having 2 Sibes.   It is much work at first, more than human twins I think, but the rewards are being doubled right now.  I know that the next thing will be challenging...adolescence.  Having children I think and raising them is kind of analogous to raising ups.  []
 
It is working for us!

See, I have a cocker spaniel now. He gets soo much attention and he's a huge part of our family. I definitely think there would be jealousy issues if we got another dog now. He was a stray and now he's treated like royalty. I wouldn't want to take any attention away from him after the tough life he's had before.

That is a real thing Amina.  Dogs do get jealous, just like human siblings.  What ever the temperament and health of your little guy there is , also is something to consider. 
 
Maybe your dog would like a little cat??  A cat is company and they are so easy to take care of.    I did that a long time ago.  The cat just loved that dog.  Although my dog was depressed when he saw what we brought home,, a sweet little kitten, he did grow fond of it.  When the dog was old and dying that cat would not leave his side.  Precious.  Also, that was the best cat I had ever had.  I think cause the cat learned dog ways or something!! []

So now we have more info to go on.  You have a resident rescue dog (age ???) for how long??.
 
I can tell you my rescue dog (golden/gordon) age 4 LOVES our new puppy.  Our older dog died last month and he was devasteated.  He has come to life with the puppy.
 
Our dog who recently died, was an only dog for 7 1/2 years, never really had dog friends.  She HATED the rescue dog and tolerated him for 1 year before she  softened , then she died. 
 
Does your cocker like dogs? 

He's about 8 years old. When we encounter other dogs, he wags and sniffs but you can tell that he's cautious. He's a lot smaller than most dogs we come by and he knows it. So whenever a dog makes a sudden movement, he always looks back at mommy to make sure everything's ok.

We've had him since last November. And at this point, I don't think we're really thinking about getting another one. It was more of a hypothetical question for the future - although, if I discover that he'd be happier with a friend, then we might consider it.

We're all allergic to cats as well, so I don't think that would be an option - although I really like them.

I'd say if your cocker isn't lonely and someone is around quite a bit,,,then why bother?  8 is getting up there,,,he may not want to deal with a puppy...they are PESTS to older dogs....I would consider an older (age 3) or so rescue as a companion.
 
I got the second for ME, becuase I knew I would die when she died.  In retrospect, I wouldn't have done it knowing what I know now.  The flip side is that #2 dog is such a wonderful boy and he wouldn't be mine if I hadn't .  And now becasue of him, we were forced to get HIM a puppy to pull him out his depression which is pulling US out of our depression.

But my guy will be here forever. He's just too good to go!

They have a blast together, ive never laughed so much

I have a question particularly about pug puppies.  I have a nine week old fawn male that I got 2 1/2 weeks ago and was considering purchasing one of his littermates after I read in a pug book to think about getting two pugs at the same time, since they thrive with other pugs.  Any pug owners out there:  Have you had any experience with litter mates doing well?  Or am I going to have the same problems I have been reading about all day?  Any response would be wonderful!

I have always had multiple dogs, but I have also alway spaced them out, so that they both weren't going through puppyhood  and socialization at the same time.  They could be just as easily be cohorts in crime as well as buddies for better behavior.....I have always had a senior dog to sort of show the younger ones the ropes...They are very effective at showing them where in the yard is the acceptable potty spot etc.  Don't know how experienced you are with dogs or puppies, but two puppies at one time could be a rough road for a novice.

We got 2 shitzhu puppies (littermates) in June and it was a BIG mistake. At first everything was great, they even slept through the night from the very start. Yes, they are bonded, but they both really want my attention and tend to be jealous of each other. We have had all sorts of behavior problems - the pups are now about 5 months and things just keep getting worse. When we are at work we gate them in the bathroom, we put everything away so that they can't destroy anything (we thought). Today when we came home they had eaten completely through the drywall - yikes! We are going to have to crate them which I hate to do for such a long period (9-10 hours), but don't feel like we have a choice. We are considering finding a new home for one of them, but just the thought makes me feel guilty. I sure wish we had stuck with one.
