I had a 8 year old pom who was an only dog, then brought in Cali, then Pixie, then Dixie and then Roxie over a period of 2 years and never had any problems with them getting along from the start. I just give them all extra attention and never leave the new one alone with the other until I know they are all ok. 5 weeks is very young to bring home a puppy, be sure to have nutrical on hand.
